Subject: [PATCH] HID: Add mapping for KEY_APP_LAUNCHER
Date:   Thu, 17 Feb 2022 05:33:57 +0000
Message-Id: <20220217053354.1.I3a7746ad05d270161a18334ae06e3b6db1a1d339@changeid>

The App Launcher key is used to bring up the Launcher menu.

This patch adds a new key definition KEY_APP_LAUNCHER and maps 0x0c02a28
usage code to this new keycode. Additionally hid-debug is adjusted to
recognize this new usage code as well.
