[PATCH] revert "swsusp add check for suspension of X controlled devices"
From: Andrew Morton <akpm@osdl.org> Revert commit ff4da2e262d2509fe1bacff70dd00934be569c66. It broke APM suspend, probably because APM doesn't switch back to a VT when suspending. Tracked down by Matt Mackall <mpm@selenic.com> Rafael sayeth: "It only fixed the theoretical issue that a quick-handed user could switch to X after processes have been frozen and before the devices are suspended. With the current userland suspend tools it shouldn't be necessary." Cc: Pavel Machek <pavel@ucw.cz> Cc: "Rafael J. Wysocki" <rjw@sisk.pl> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
