Ulf Hansson 8dc22842bd memstick: rtsx_usb_ms: Manage runtime PM when accessing the device ... commit 9158cb29e7c2f10dd325eb1589f0fe745a271257 upstream. Accesses to the rtsx usb device, which is the parent of the rtsx memstick device, must not be done unless it's runtime resumed. This is currently not the case and it could trigger various errors. Fix this by properly deal with runtime PM in this regards. This means making sure the device is runtime resumed, when serving requests via the ->request() callback or changing settings via the ->set_param() callbacks.
