[119/152] mmc: Fix re-probing with PM_POST_RESTORE notification

From: Greg KH

2.6.36-stable review patch. If anyone has any objections, please let us know.

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

From: Takashi Iwai <tiwai@xxxxxxx>

commit 274476f8fe0b6ac9bac542cc39de12c3dd0f43f6 upstream.

In the error-path where PM notifies PM_POST_RESTORE, the rescan-blockage
should be cleared as well. Otherwise it'll be never re-probed.

Also, as a bonus, this fixes a bug in S4 with user-mode suspend in the
current code, as it sends PM_POST_RESTORE instead of
PM_POST_HIBERNATION wrongly.
