Subject: [PATCH] HID: add mapping for camera access keys
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
HUTRR72 added 3 new usage codes for keys that are supposed to enable,
disable and toggle camera access. These are useful, considering many
laptops today have key(s) for toggling access to camera.
This patch adds new key definitions for KEY_CAMERA_ACCESS_ENABLE,
KEY_CAMERA_ACCESS_DISABLE and KEY_CAMERA_ACCESS_TOGGLE. Additionally
hid-debug is adjusted to recognize this new usage codes as well.
