[PATCH] HID: Add mapping for KEY_APP_LAUNCHER

From: William Mahon
Date: Thu Feb 17 2022 - 00:34:08 EST


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.
