Subject: [PATCH 3.12 015/111] Input: cros_ec_keyb - fix clearing keyboard state on wakeup

From: Tomeu Vizoso <tomeu.vizoso@...labora.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit ef30a406468a3eae007210ae0dc5ed8d5eb59b7d upstream.

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.
