Subject: Input: cros_ec_keyb - remove check before calling pm_wakeup_event
X-Git-Tag: v4.19~15^2~12^2~48
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=925ffff2ea8b408428f2558074af92cf31325156;p=platform%2Fkernel%2Flinux-rpi.git

Input: cros_ec_keyb - remove check before calling pm_wakeup_event

Remove the unnecessary check before calling pm_wakeup_event. If the
device is not wake enabled, this call is no-op anyway.
