commit e36ce99e upstream. Module test reports: temp1_max: Suspected overflow: [160000 vs. 0] temp1_min: Suspected overflow: [160000 vs. 0] This is seen because the values passed when writing temperature limits are unbound. Reviewed-by:

commit 13edb767 upstream. If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/hwmon/scpi-hwmon.ko | grep alias $ After this patch: $ modinfo drivers/hwmon/scpi-hwmon.ko | grep alias alias: of:N*T*Carm,scpi-sensorsC* alias: of:N*T*Carm,scpi-sensors Signed-off-by:

commit 328cf692 upstream. If CONFIG_ETRAX_AXISFLASHMAP is not configured, the flash rescue image object file is empty. With recent versions of binutils, this results in the following build error. cris-linux-objcopy: error: the input file 'arch/cris/boot/rescue/rescue.o' has no sections This is seen, for example, when trying to build cris:allnoconfig with recently generated toolchains. Since it does not make sense to build a flash rescue image if there is no flash, only build it if CONFIG_ETRAX_AXISFLASHMAP is enabled. Reported-by:

[resolves a messed up backport, so no matching upstream commit] The backport of upstream commit 777c6e0d ("hotplug: Make register and unregister notifier API symmetric") to linux-4.4.y introduced a harmless warning in 'allnoconfig' builds as spotted by kernelci.org: kernel/cpu.c:226:13: warning: 'cpu_notify_nofail' defined but not used [-Wunused-function] So far, this is the only stable tree that is affected, as linux-4.6 and higher contain commit 98458172 ("cpu/hotplug: Split out cpu down functions") that makes the function used in all configurations, while older longterm releases so far don't seem to have a backport of 777c6e0d. The fix for the warning is trivial: move the unused function back into the #ifdef section where it was before.

commit 19ec3123 upstream. Let's call dwc3_ep0_prepare_one_trb() explicitly because there are occasions where we will need more than one TRB to handle an EP0 transfer. A follow-up patch will fix one bug related to multiple-TRB Data Phases when it comes to mapping/unmapping requests for DMA. Reported-by:

commit 7931ec86 upstream. For now this is just a cleanup patch, no functional changes. We will be using the new function to fix a bug introduced long ago by commit 0416e494 ("usb: dwc3: ep0: correct cache sync issue in case of ep0_bounced") and further worsened by commit c0bd5456 ("usb: dwc3: ep0: handle non maxpacket aligned transfers > 512") Reported-by:

commit d6214592 upstream. commit 0416e494 ("usb: dwc3: ep0: correct cache sync issue in case of ep0_bounced") introduced a bug where we would leak DMA resources which would cause us to starve the system of them resulting in failing DMA transfers. Fix the bug by making sure that we always unmap EP0 requests since those are *always* mapped.

commit b321a38d upstream. The oversampling ratio is controlled using the oversampling pins, OS [2:0] with OS2 being the MSB control bit, and OS0 the LSB control bit. The gpio connected to the OS2 pin is not being set correctly, only OS0 and OS1 pins are being set. Fix the typo to allow proper control of the oversampling pins. Signed-off-by:

commit 3c3dd1e0 upstream. Function klsi_105_open() calls usb_control_msg() (to "enable read") and checks its return value. When the return value is unexpected, it only assigns the error code to the return variable retval, but does not terminate the exception path. This patch fixes the bug by inserting "goto err_generic_close;" when the call to usb_control_msg() fails. Fixes: 1da177e4 ("Linux-2.6.12-rc2") Signed-off-by:

commit 1c111b6c upstream. Current abort operation has race. xhci_handle_command_timeout() xhci_abort_cmd_ring() xhci_write_64(CMD_RING_ABORT) xhci_handshake(5s) do { check CMD_RING_RUNNING udelay(1) ... COMP_CMD_ABORT event COMP_CMD_STOP event xhci_handle_stopped_cmd_ring() restart cmd_ring CMD_RING_RUNNING become 1 again } while () return -ETIMEDOUT xhci_write_64(CMD_RING_ABORT) /* can abort random command */ To do abort operation correctly, we have to wait both of COMP_CMD_STOP event and negation of CMD_RING_RUNNING. But like above, while timeout handler is waiting negation of CMD_RING_RUNNING, event handler can restart cmd_ring. So timeout handler never be notice negation of CMD_RING_RUNNING, and retry of CMD_RING_ABORT can abort random command (BTW, I guess retry of CMD_RING_ABORT was workaround of this race). To fix this race, this moves xhci_handle_stopped_cmd_ring() to xhci_abort_cmd_ring(). And timeout handler waits COMP_CMD_STOP event. At this point, timeout handler is owner of cmd_ring, and safely restart cmd_ring by using xhci_handle_stopped_cmd_ring(). [FWIW, as bonus, this way would be easily extend to add CMD_RING_PAUSE operation] [locks edited as patch is rebased on other locking fixes -Mathias] Signed-off-by:

commit fde1faf8 upstream. A static usb-serial-driver structure that is used to initialise the interrupt URB was modified during probe depending on the currently probed device type, something which could break a parallel probe of a device of a different type. Fix this up by overriding the default completion callback for MCS7715 devices in attach() instead. We may want to use two usb-serial driver instances for the two types later.
