[PATCH] Corgi Touchscreen: Code cleanup / fixes
Clean up some Corgi Touchscreen logic and merge the repeat calls to w100fb_blanking() in anticipation of the w100fb patch. Fix a pm_message_t reference. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
