[Luis Henriques]

3.16.7-ckt3 -stable review patch.  If anyone has any objections, please let me know.

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

From: Joonyoung Shim <jy0922.shim at samsung.com>

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().
