commit 8128a31eaadbcdfa37774bbd28f3f00bac69996a upstream. c2port_device_register() never returns NULL, it uses error pointers.

cxl: Fix error path on bad ioctl

2017-06-14T11:16:24+00:00

commit cec422c11caeeccae709e9942058b6b644ce434c upstream. Fix error path if we can't copy user structure on CXL_IOCTL_START_WORK ioctl. We shouldn't unlock the context status mutex as it was not locked (yet).

mei: request async autosuspend at the end of enumeration

2017-01-09T07:07:47+00:00

commit d5f8e166c25750adc147b0adf64a62a91653438a upstream. pm_runtime_autosuspend can take synchronous or asynchronous paths, Because we are calling pm_runtime_mark_last_busy just before this most of the cases it takes the asynchronous way. However, when the FW or driver resets during already running runtime suspend, the call will result in calling to the driver's rpm callback and results in a deadlock on device_lock. The simplest fix is to replace pm_runtime_autosuspend with asynchronous pm_request_autosuspend. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: me: disable driver on SPT SPS firmware

commit 8c57cac1457f3125a5d13dc03635c0708c61bff0 upstream. Sunrise Point PCH with SPS Firmware doesn't expose working MEI interface, we need to quirk it out. The SPS Firmware is identifiable only on the first PCI function of the device. Tested-by: Sujith Pandel Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman
