[PATCH] swsusp: do not change log level during suspend/resume
Prevent the kernel from setting the log level to 10 unconditionally during suspend/resume which was needed in the past for debugging, but generally is undesirable. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
