Subject: [PATCH] mmc: Fix re-probing after hibernation
Date: Wed, 8 Dec 2010 16:23:59 +0100 [thread overview]
Message-ID: <1291821839-15088-1-git-send-email-tiwai@suse.de> (raw)
The commit 4c2ef25fe0b847d2ae818f74758ddb0be1c27d8e
mmc: fix all hangs related to mmc/sd card insert/removal during
suspend/resume
introduced a bug where the device probing no longer works after
hibernation. This was because the pm notifier expects
PM_POST_HIBERNATION call while the system sends PM_POST_RESTORE
instead, thus disable_rescan is kept as 1.
