commit f3bb2376 upstream. This avoids a harmless randconfig warning I get when USB_NET_CDC_SUBSET is enabled, but all of the more specific drivers are not: drivers/net/usb/cdc_subset.c:241:2: #warning You need to configure some hardware for this driver The current behavior is clearly intentional, giving a warning when a user picks a configuration that won't do anything good. The only reason for even addressing this is that I'm getting close to eliminating all 'randconfig' warnings on ARM, and this came up a couple of times. My workaround is to not even build the module when none of the configurations are enable. Alternatively we could simply remove the #warning (nothing wrong for compile-testing), turn it into a runtime warning, or change the Kconfig options into a menu to hide CONFIG_USB_NET_CDC_SUBSET.

commit b93f342d upstream. The exynos random driver uses #ifdef to check for CONFIG_PM, but then uses SIMPLE_DEV_PM_OPS, which leaves the references out when CONFIG_PM_SLEEP is not defined, so we get a warning with PM=y && PM_SLEEP=n: drivers/char/hw_random/exynos-rng.c:166:12: error: 'exynos_rng_suspend' defined but not used [-Werror=unused-function] drivers/char/hw_random/exynos-rng.c:171:12: error: 'exynos_rng_resume' defined but not used [-Werror=unused-function] This removes the incorrect #ifdef and instead uses a __maybe_unused annotation to let the compiler know it can silently drop the function definition.

commit 24ed78dc upstream. The sm712fb framebuffer driver encloses the power-management functions in #ifdef CONFIG_PM, but the smtcfb_pci_suspend/resume functions are only really used when CONFIG_PM_SLEEP is also set, as a frequent gcc warning shows: fbdev/sm712fb.c:1549:12: warning: 'smtcfb_pci_suspend' defined but not used fbdev/sm712fb.c:1572:12: warning: 'smtcfb_pci_resume' defined but not used The driver also avoids using the SIMPLE_DEV_PM_OPS macro when CONFIG_PM is unset, which is redundant. This changes the driver to remove the #ifdef and instead mark the functions as __maybe_unused, which is a nicer anyway, as it provides build testing for all the code in all configurations and is harder to get wrong.

commit 5d06ee20 upstream. When a user calls 'make -s', we can assume they don't want to see any output except for warnings and errors, but instead they see this for a warning free build: ### ### Now generating an X.509 key pair to be used for signing modules. ### ### If this takes a long time, you might wish to run rngd in the ### background to keep the supply of entropy topped up. It ### needs to be run as root, and uses a hardware random ### number generator if one is available. ### Generating a 4096 bit RSA private key .................................................................................................................................................................................................................................++ ..............................................................................................................................++ writing new private key to 'certs/signing_key.pem' ----- ### ### Key pair generated. ### The output can confuse simple build testing scripts that just check for an empty build log. This patch silences all the output: - "echo" is changed to "@$(kecho)", which is dropped when "-s" gets passed - the openssl command itself is only printed with V=1, using the $(Q) macro - The output of openssl gets redirected to /dev/null on "-s" builds.

commit b54729b6 upstream. The s6e8ax0 suspend/resume functions are hidden inside of an #ifdef when CONFIG_PM is set to avoid unused function warnings, but they call some other functions that nothing else calls, and we get warnings about those: drivers/video/fbdev/exynos/s6e8ax0.c:449:13: error: 's6e8ax0_sleep_in' defined but not used [-Werror=unused-function] drivers/video/fbdev/exynos/s6e8ax0.c:485:13: error: 's6e8ax0_display_off' defined but not used [-Werror=unused-function] This marks the PM functions as __maybe_unused so the compiler can silently drop them when they are not referenced.

commit f5f92b36 upstream. MTD allows compile-time configuration of the possible CFI geometry settings that are allowed by the kernel, but that includes a couple of invalid configurations, where no bank width or no interleave setting is allowed. These are then caught with a compile-time warning: include/linux/mtd/cfi.h:76:2: warning: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work. include/linux/mtd/map.h:145:2: warning: #warning "No CONFIG_MTD_MAP_BANK_WIDTH_xx selected. No NOR chip support can work" This is a bit annoying for randconfig tests, and can be avoided if we change the Kconfig logic to always select the simplest configuration when no other one is enabled.

commit 1873315f upstream. By convention, the FIFO address we pass using dmaengine_slave_config is a physical address in the form that is understood by the DMA engine, as a dma_addr_t, phys_addr_t or resource_size_t. The sh_flctl driver however passes a virtual __iomem address that gets cast to dma_addr_t in the slave driver. This happens to work on shmobile because that platform sets up an identity mapping for its MMIO regions, but such code is not portable to other platforms, and prevents us from ever changing the platform mapping or reusing the driver on other architectures like ARM64 that might not have the mapping. We also get a warning about a type mismatch for the case that dma_addr_t is wider than a pointer, i.e. when CONFIG_LPAE is set: drivers/mtd/nand/sh_flctl.c: In function 'flctl_setup_dma': drivers/mtd/nand/sh_flctl.c:163:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] cfg.dst_addr = (dma_addr_t)FLDTFIFO(flctl); This changes the driver to instead pass the physical address of the FIFO that is extracted from the MMIO resource, making the code more portable and avoiding the warning.

commit 1f62ff34 upstream. dev_dbg_ratelimited() is a macro that ignores its first argument when DEBUG is not set, which can lead to unused variable warnings: ethernet/mellanox/mlxsw/pci.c: In function 'mlxsw_pci_cqe_sdq_handle': ethernet/mellanox/mlxsw/pci.c:646:18: warning: unused variable 'pdev' [-Wunused-variable] ethernet/mellanox/mlxsw/pci.c: In function 'mlxsw_pci_cqe_rdq_handle': ethernet/mellanox/mlxsw/pci.c:671:18: warning: unused variable 'pdev' [-Wunused-variable] The macro already ensures that all its other arguments are silently ignored by the compiler without triggering a warning, through the use of the no_printk() macro, but the dev argument is not passed into that. This changes the definition to use the same trick as no_printk() with an if(0) that leads the compiler to not evaluate the side-effects but still see that 'dev' might not be unused. Signed-off-by:

commit 0633e123 upstream. The uio_mem structure has a member that is a phys_addr_t, but can be a number of other types too. The target core driver attempts to assign a pointer from vmalloc() to it, by casting it to phys_addr_t, but that causes a warning when phys_addr_t is longer than a pointer: drivers/target/target_core_user.c: In function 'tcmu_configure_device': drivers/target/target_core_user.c:906:22: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] This adds another cast to uintptr_t to shut up the warning. A nicer fix might be to have additional fields in uio_mem for the different purposes, so we can assign a pointer directly. Signed-off-by:

commit 62a6abdd upstream. When dma_addr_t is 64-bit, we get a warning about an invalid cast in the call to ux500_dma_is_compatible() from ux500_dma_channel_program(): drivers/usb/musb/ux500_dma.c: In function 'ux500_dma_channel_program': drivers/usb/musb/ux500_dma.c:210:51: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] if (!ux500_dma_is_compatible(channel, packet_sz, (void *)dma_addr, len)) The problem is that ux500_dma_is_compatible() is called from the main musb driver on the virtual address, but here we pass in a DMA address, so the types are fundamentally different but it works because the function only checks the alignment of the buffer and that is the same. We could work around this by adding another cast, but I have checked that the buffer we get passed here is already checked before it gets mapped, so the second check seems completely unnecessary and removing it must be the cleanest solution.

commit d282e2b3 upstream. The initio driver has for many years had two copies of the same module device table. One of them is also used for registering the other driver, the other one is entirely useless after the large scale cleanup that Alan Cox did back in 2007. The compiler warns about this whenever the driver is built-in: drivers/scsi/initio.c:131:29: warning: 'i91u_pci_devices' defined but not used [-Wunused-variable] This removes the extraneous table and the warning.

commit e4106a7c upstream. Add __init attribute on functions that are only called from other __init functions and that are not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the functions are put in the .text.unlikely segment. Declaring them as __init will cause them to be put in the .init.text and to disappear after initialization. The result of objdump -x on the functions before the change is as follows: 00000000000001bc l F .text.unlikely 00000000000006a2 ck804xrom_init_one.isra.1 00000000000001aa l F .text.unlikely 0000000000000764 esb2rom_init_one.isra.1 00000000000001db l F .text.unlikely 0000000000000716 ichxrom_init_one.isra.1 And after the change it is as follows: 0000000000000000 l F .init.text 000000000000069d ck804xrom_init_one.isra.1 0000000000000000 l F .init.text 000000000000075f esb2rom_init_one.isra.1 0000000000000000 l F .init.text 0000000000000711 ichxrom_init_one.isra.1 Done with the help of Coccinelle. The semantic patch checks for local static non-init functions that are called from an __init function and are not called from any other function. Note that in each case, the function is stored in the probe field of a pci_driver structure, but this code is under an #if 0. The #if 0s have been unchanged since 2009 at the latest. Signed-off-by:

commit 3312c951 upstream. When CONFIG_LBDAF is not set, sector_t is only 32-bits wide, which means we cannot have devices with more than 2TB, and the code that is trying to handle compatibility support for large devices in md version 0.90 is meaningless but also causes a compile-time warning: drivers/md/md.c: In function 'super_90_load': drivers/md/md.c:1029:19: warning: large integer implicitly truncated to unsigned type [-Woverflow] drivers/md/md.c: In function 'super_90_rdev_size_change': drivers/md/md.c:1323:17: warning: large integer implicitly truncated to unsigned type [-Woverflow] This adds a check for CONFIG_LBDAF to avoid even getting into this code path, and also adds an explicit cast to let the compiler know it doesn't have to warn about the truncation.

After we have called both, all data is correct, but the first of the two reads uninitialized data for the type field and writes it back before it gets overwritten. This works around the warning by initializing the k_offset_v2 through the slightly larger memcpy(). [JK: Remove now unused define and make it obvious we initialize the key] Signed-off-by:

The IOSF_MBI option requires PCI support, without it we get a harmless Kconfig warning when it gets selected by PUNIT_ATOM_DEBUG: warning: (X86_INTEL_LPSS && SND_SST_IPC_ACPI && MMC_SDHCI_ACPI && PUNIT_ATOM_DEBUG) selects IOSF_MBI which has unmet direct dependencies (PCI) This adds another dependency to avoid the warning.
