Subject: [PATCH] mmc: sh_mmcif: ensure run-time suspend call is processed
before suspend
With this post-v2.6.35 change applied:
commit a0a1a5fd4fb15ec61117c759fe9f5c16c53d9e9c
Author: Tejun Heo <tj@kernel.org>
Date: Tue Jun 29 10:07:12 2010 +0200
workqueue: reimplement workqueue freeze using max_active
freeze_workqueues_begin() was introduced and workqueue now gets frozen
before device drivers suspend operations.
We have to ensure that run-time PM suspend operation completes before
system-wide suspend is started.
