2016-10-28memstick: rtsx_usb_ms: Manage runtime PM when accessing the deviceUlf Hansson
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.

2016-10-28memstick: rtsx_usb_ms: Runtime resume the device when polling for cardsAlan Stern
commit 796aa46adf1d90eab36ae06a42e6d3f10b28a75c 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. Therefore when the rtsx_usb_ms driver polls for inserted memstick cards, let's add pm_runtime_get|put*() to make sure accesses is done when the rtsx usb device is runtime resumed.
