[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."
