commit 8515bac0 upstream. Mass storage function created via configfs always reports eight LUNs to the hosts even if only one LUN has been configured. Adjust the number when the USB function is allocated based on LUNs that user has created. Tested-by:

commit b4c21f0b upstream. commit f563d230 ("usb: gadget: composite: add req_match method to usb_function") accesses cdev->config even before set config is invoked causing a NULL pointer dereferencing error while running Lecroy Mass Storage Compliance test.

commit 4724e271 upstream. The USB phy should initialize with power-off, and will be powered on by the USB system when a cable connection is detected. Having this pm_runtime_get_sync() during probe causes the phy to *always* be powered on. Removing it returns to sensible power management. Fixes: 96be39abSigned-off-by:

commit fb6d1f7d upstream. Fix USB 3.0 devices lost in NOTATTACHED state after a hub port reset. Dissolve the function hub_port_finish_reset() completely and divide the actions to be taken into those which need to be done after each reset attempt and those which need to be done after the full procedure is complete, and place them in the appropriate places in hub_port_reset(). Also, remove an unneeded forward declaration of hub_port_reset(). Verbose Problem Description: USB 3.0 devices may be "lost for good" during a hub port reset. This makes Linux unable to boot from USB 3.0 devices in certain constellations of host controllers and devices, because the USB device is lost during initialization, preventing the rootfs from being mounted. The underlying problem is that in the affected constellations, during the processing inside hub_port_reset(), the hub link state goes from 0 to SS.inactive after the initial reset, and back to 0 again only after the following "warm" reset. However, hub_port_finish_reset() is called after each reset attempt and sets the state the connected USB device based on the "preliminary" status of the hot reset to USB_STATE_NOTATTACHED due to SS.inactive, yet when the following warm reset is complete and hub_port_finish_reset() is called again, its call to set the device to USB_STATE_DEFAULT is blocked by usb_set_device_state() which does not allow taking USB devices out of USB_STATE_NOTATTACHED state. Thanks to Alan Stern for guiding me to the proper solution and how to submit it.

commit aebda618 upstream. This fixes an issue introduced in commit b23c8439 (usb: dwc3: gadget: fix DEPSTARTCFG for non-EP0 EPs) that made sure we would only use DEPSTARTCFG once per SetConfig. The trick is that we should use one DEPSTARTCFG per SetConfig *OR* SetInterface. SetInterface was completely missed from the original patch. This problem became aparent after commit 76e838c9 (usb: dwc3: gadget: return error if command sent to DEPCMD register fails) added checking of the return status of device endpoint commands. 'Set Endpoint Transfer Resource' command was caught failing occasionally. This is because the Transfer Resource Index was not getting reset during a SET_INTERFACE request. Finally, to fix the issue, was we have to do is make sure that our start_config_issued flag gets reset whenever we receive a SetInterface request. To verify the problem (and its fix), all we have to do is run test 9 from testusb with 'testusb -t 9 -s 2048 -a -c 5000'. Tested-by:

commit e18b7975 upstream. In case of non-Isochronous transfers, we don't want to clear DWC3_EP_BUSY flag until XferComplete event. That's because XferInProgress was only enabled so we can recycle TRBs and usb_requests quicker, but there are still other pending requests being transferred. In order to make sure we don't allow for another StartTransfer command while the HW is still processing other transfers, we must keep DWC3_EP_BUSY flag set and this what this patch does. Fixes: f3af3651 (usb: dwc3: gadget: always enable IOC on bulk/interrupt transfers) Reported-by:

commit af34d637 upstream. Since no longer limiting max_sectors to BLK_DEF_MAX_SECTORS (commit 34b48db6), data corruption may occur on ST380013AS drive configured on 82801JI (ICH10 Family) SATA controller. This patch will allow the driver to limit max_sectors as before # cat /sys/block/sdb/queue/max_sectors_kb 512 I was able to double the max_sectors_kb value up to 16384 on linux-4.2.0-rc2 before seeing corruption, but seems safer to use previous limit. Without this patch max_sectors_kb will be 32767. tj: Minor comment update. Reported-by:

commit 5d3abf8f upstream. Some devices advertise support for the READ/WRITE LOG DMA EXT commands but fail when we try to issue them. This can lead to queued TRIM being unintentionally disabled since the relevant feature flag is located in a general purpose log page. Fall back to unqueued READ LOG EXT if the DMA variant fails while reading a log page. Signed-off-by:

commit d531be2c upstream. I have a ST4000DM000 disk. If Linux is booted while the disk is spun down, the command that sets transfer mode causes the disk to spin up. The spin-up takes longer than the default 5s timeout, so the command fails and timeout is reported. Fix this by increasing the timeout to 15s, which is enough for the disk to spin up. Signed-off-by:

commit 0574eab3 upstream. I tried to fix this before and submitted a working patch, but after some discussion we came up with what seemed to be a nicer solution, resulting in commit 3d4cf65e ("ASoC: omap: fix up SND_OMAP_SOC_OMAP_ABE_TWL6040 dependency"). Unfortunately, that version was incomplete, and we still get this build error: drivers/clk/clk-palmas.c:46:16: error: field 'hw' has incomplete type drivers/clk/clk-palmas.c: In function 'to_palmas_clks_info': drivers/clk/clk-palmas.c:54:74: warning: initialization from incompatible pointer type [-Winc This happens only in randconfig builds that turn on MFD_PALMAS on a platform other than OMAP2+ when COMPILE_TEST is set but COMMON_CLK is not. The new approach is only 'select COMMON_CLK_PALMAS' if we know that we are on an OMAP5 platform and MFD_PALMAS is already set. This patch has survived thousands of randconfig builds and I don't see a remaining hole in the logic. Fixes: 3d4cf65e ("ASoC: omap: fix up SND_OMAP_SOC_OMAP_ABE_TWL6040 dependency") Signed-off-by:

commit a7310c49 upstream. Compile-tests show a warning for the newly added SND_SOC_STORM symbol: warning: (SND_SOC_STORM) selects SND_SOC_LPASS_CPU which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && SND_SOC_QCOM) The problem is that it can be selected for COMPILE_TEST on non-QCOM builds, but the symbols it selects have a dependency. Dropping the dependencies makes it work without warnings and no other side-effects, because these are not user-visible. Signed-off-by:
