[PATCH AUTOSEL 4.4 2/3] Input: cros_ec_keyb - send 'scancodes' in addition to key events

[Sasha Levin]

From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>

[ Upstream commit 80db2a087f425b63f0163bc95217abd01c637cb5 ]

To let userspace know what 'scancodes' should be used in EVIOCGKEYCODE
and EVIOCSKEYCODE ioctls, we should send EV_MSC/MSC_SCAN events in
addition to EV_KEY/KEY_* events. The driver already declared MSC_SCAN
capability, so it is only matter of actually sending the events.
