mei: remove dev_err message on an unsupported ioctl

2018-04-08T09:52:00+00:00

commit bb0829a741792b56c908d7745bc0b2b540293bcc upstream. Currently the driver spams the kernel log on unsupported ioctls which is unnecessary as the ioctl returns -ENOIOCTLCMD to indicate this anyway. I suspect this was originally for debugging purposes but it really is not required so remove it. Signed-off-by: Colin Ian King Cc: stable Signed-off-by: Greg Kroah-Hartman

mei: return error on notification request to a disconnected client

[ Upstream commit 7c47d2ca0feca767479329da23523ed798acb854 ] Request for a notification from a disconnected client will be ignored silently by the FW but the caller should know that the operation hasn't succeeded.

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

commit 582ab27a063a506ccb55fc48afcc325342a2deba upstream. NFC version reply size checked against only header size, not against full message size.
