Subject: [PATCH] Input: cros_ec_keyb - send 'scancodes' in addition to key events
Date: Mon, 7 Dec 2020 17:43:21 -0800	[thread overview]
Message-ID: <X87aOaSptPTvZ3nZ@google.com> (raw)

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.
