Subject: [PATCH 1/2] PM/runtime: fix comment for rpm_suspend
Date: Wed, 12 Oct 2011 11:53:32 +0800 [thread overview]
Message-ID: <1318391613-24364-1-git-send-email-ming.lei@canonical.com> (raw)
From: Ming Lei <ming.lei@canonical.com>
This patch fix comments for rpm_suspend:
- 'Cancel a pending idle notification' should be put before, also
should be changed as 'Cancel a pending idle notification,
autosuspend or suspend'
- after suspend succeeded, idle notification for the device has
been removed, so update comment for it
