[119/152] mmc: Fix re-probing with PM_POST_RESTORE notification
From: Greg KH
Date: Wed Jan 05 2011 - 19:39:21 EST
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.
