commit 3f5ceec9 upstream. fdt_translate_address() returns OF_BAD_ADDR on error. It is defined as a u64 value, so the variable "addr" should be defined as u64 as well. Fixes: fb11ffe7 ("of/fdt: add FDT serial scanning for earlycon") Signed-off-by:

This change just reverts the logic to the old behavior to avoid the crash. Fixes: 8b13eddf ("netfilter: refactor NAT redirect IPv4 to use it from nf_tables") Signed-off-by:

commit 76d63c2b upstream. The "compatible" property text contradicts even the example given in the MMCIF binding document itself; moreover, the Renesas MMCIF driver only matches on the generic "compatible" string and doesn't look for the SoC specific strings at all.

commit cc6a7aab upstream. The gss_key_timeout() function causes a harmless warning in some configurations, e.g. ARM imx_v6_v7_defconfig with gcc-5.2, if the compiler cannot figure out the state of the 'expire' variable across an rcu_read_unlock(): net/sunrpc/auth_gss/auth_gss.c: In function 'gss_key_timeout': net/sunrpc/auth_gss/auth_gss.c:1422:211: warning: 'expire' may be used uninitialized in this function [-Wmaybe-uninitialized] To avoid this warning without adding a bogus initialization, this rewrites the function so the comparison is done inside of the critical section. As a side-effect, it also becomes slightly easier to understand because the implementation now more closely resembles the comment above it. Signed-off-by:

commit 468a3208 upstream. Since the "Switch driver to use transfer_one" change, the cs_change behavior has changed and a channel chip select can still be asserted when changing channel from a previous last transfer in a message having the cs_change attribute. Since there is no sense having multiple chip select being asserted at the same time, disable all the remaining forced chip selects in a the prepare_message called right before a spi_transfer_one_message call. It ignores the current channel configuration in order to keep the possibility to leave the chip select asserted between messages. It fixes this bug on a DM8168 SoC ES2.1 Soc and an OMAP4 ES2.1 SoC. It was hanging all the other channels transfers when a CHCONF_FORCE is present on the wrong channel. Fixes: b28cb941 ("spi: omap2-mcspi: Switch driver to use transfer_one") Signed-off-by:

commit 5d1e6235 upstream.

This was accidentally disabled by commit 4b096ac1 ("drm: revamp locking around fb creation/destruction"). Thus, drm_framebuffer_init() pretends success if drm_mode_object_get() failed.

commit ce938001 upstream. The LDO1 driver is using the arizona_of_get_named_gpio helper function which will return 0 if an error was encountered whilst parsing the GPIO, as under the pdata scheme 0 was not being treated as a valid GPIO. However, since the regulator framework was expanded to allow the use of GPIO 0 this causes us to attempt to register GPIO 0 when we encountered an error parsing the device tree. This patch uses of_get_named_gpio directly and sets the ena_gpio_initialized flag based on the return value.

commit 58b0497d upstream. The requested bit rate can be outside the range supported by the driver. The maximum bit rate this driver supports at the moment is 400Khz. If the requested bit rate is larger than the maximum supported by the driver, set the bitrate to the maximum supported before bitrate_khz is calculated. Maximum speed supported by the driver can be increased to 1Mhz by adding support for "fast plus mode" in the future.

commit 987008db upstream. Currently, after determining the minimum value for the High period (TCKH) the remainder of the internal clock pulses is set as the Low period (TCKL). This causes the i2c clock duty cycle to be much less than 50%. Modify the starting position to TCKH and TCKL at 50% of the internal clock, and adjusts the TCKH and TCKL values from there should the minimum value for TCKL not be met.

commit 0e59378b upstream. The code to read from the master read fifo, and write to the master write fifo, checks a bit in an SCB register before every byte to ensure that the fifo is not full (write fifo) or empty (read fifo). Due to clock domain crossing inside the SCB block the updated value of this bit is only visible after 2 cycles. The scb_wr_rd_fence() function does 2 dummy writes (to the read-only revision register), and it's called before reading from or writing to the fifos to ensure that subsequent reads of the fifo status bits do not read stale values. As the 2 dummy writes are required in all versions of the ip, the version check is dropped. Fixes: commit 27bce457 ("i2c: img-scb: Add Imagination Technologies I2C SCB driver") Signed-off-by:

commit 850dcc4d upstream. After a packet has been encapsulated by a tunnel we should use the tunnel sockets local multicast loopback flag to control if the encapsulated packet should be locally loopback back. Pass sk into ip_local_out_sk so that in the rare case we are dealing with a tunneled packet whose tunnel destination address is a multicast address the kernel properly decides to loopback this packet. In practice I don't think this matters as ip_queue_xmit is used by tcp, l2tp and sctp none of which I am aware of uses ip level multicasting as they are all point to point communications protocols. Let's fix this before someone uses ip_queue_xmit for a tunnel protocol that does use multicast. Fixes: aad88724 ("ipv4: add a sock pointer to dst->output() path.")

commit 38cb5245 upstream. This fixes a typo : We want to store the NAPI id on child socket. Presumably nobody really uses busy polling, on short lived flows. Fixes: 3d97379a ("tcp: move sk_mark_napi_id() at the right place") Signed-off-by:

commit 39416677 upstream. We replace __fls() by __ffs() since we have to find a *minimum* data width that satisfies both source and destination. While here, rename dwc_fast_fls() to dwc_fast_ffs() which it really is. Fixes: 4c2d56c5 (dw_dmac: introduce dwc_fast_fls()) Signed-off-by:

commit 90adf98d upstream. Since commit 1c6c6952 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. scripts/coccinelle/misc/irqf_oneshot.cocci detected this issue.

commit 97bce7e0 upstream. Module crc32c-intel uses a special read-only data section named .rotata. This section is defined for K_table, and its name seems to be a spelling mistake for .rodata. Fixes: 473946e6 ("crypto: crc32c-pclmul - Shrink K_table to 32-bit words") Signed-off-by:

commit c4047f53 upstream. Redo commit ed1acc8c. Commit 822b3b2e ("net: Add max rate tx queue attribute") moved get_netdev_queue_index around, but kept the old version. Probably because of a reuse of the original patch from before Eric's change to that function. Remove one inline keyword, and no need for a loop to find an index into a table. Signed-off-by:

ALSA: pcm: remove structure member of 'struct snd_pcm_hwptr_log *' type because this structure had been removed commit 0052b7dc upstream. This structure was added by 4d96eb25 ('ALSA: pcm_lib - add possibility to log last 10 DMA ring buffer positions') to store PCM pointers information of latest 10 pointer movements (=XRUN_LOG_CNT). When CONFIG_SND_PCM_XRUN_DEBUG is configured, 'struct snd_pcm_runtime' has 'hwptr_log' member with a pointer to the structure. When calling xrun_log() in pcm_lib.c, the structure was allocated to the pointer. When calling snd_pcm_detach_substream() in pcm.c, the allocated pointer is released. In f5914908 ('ALSA: pcm: Replace PCM hwptr tracking with tracepoints'), the pointer logging is replaced with using Linux Kernel Tracepoints. The structure was also removed, while it's just declared. The member and kfree still remains. This commit removes the member and related codes. I think this was overlooked because it brings no errors/warnings to C compilers.
