From: Ben Hutchings
Date: Fri Dec 12 2014 - 02:01:01 EST


3.2.65-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Joonyoung Shim <jy0922.shim@xxxxxxxxxxx>

commit 526a4045c60fbaede88ec95a69a73059dff02160 upstream.

The usb device will autoresume from choose_wakeup() if it is
autosuspended with the wrong wakeup setting, but below errors occur
because usb3503 misc driver will switch to standby mode when suspended.

As add USB_QUIRK_RESET_RESUME, it can stop setting wrong wakeup from
autosuspend_check().
