[PATCH 17/20] omapfb: suspend/resume only if FB device is already initialized

From: Imre Deak
Date: Wed Jun 24 2009 - 07:38:31 EST


From: Jouni HÃgander <jouni.hogander@xxxxxxxxx>

Check wether fbdev is NULL in suspend / resume functions. Fbdev is
NULL, if there is no lcd or it is not enabled in configuration.
