Subject: PM / Hibernate: When failed, in_suspend should be reset
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5262a47502adcfc3a64403120768f528418a3b79;p=deliverable%2Flinux.git

PM / Hibernate: When failed, in_suspend should be reset

When hibernation failed due to an error in swsusp_write() called by
hibernate(), it skips calling "power_down()" and returns. When
hibernate() is called again (probably after fixing up so that
swsusp_write() wouldn't fail again), before "in_suspend = 1" of
create_image is called, in_suspend should be 0. However, because
hibernate() did not reset "in_suspend" after a failure, it's already 1.

This patch fixes such inconsistency of "in_suspend" value.
