[PATCH] Input: cros_ec_keyb - Clear keyboard state only when it hasn't been a wake source

From: Tomeu Vizoso
Date: Wed Mar 25 2015 - 12:05:03 EST


As the comment right before explains, the keyboard state is to be
cleared only if the EC wasn't a wakeup source in the last suspend.

Without this commit, there's an unneeded delay when resuming from
suspend and we also lose the key that was pressed while suspended.
