Subject: [PATCH] HID: Add mapping for KEY_DICTATE
Date:   Thu, 17 Feb 2022 04:14:54 +0000
Message-Id: <20220217041427.1.I5dbf50eb1a7a6734ee727bda4a8573358c6d3ec0@changeid>

Numerous keyboards are adding dicate keys which allows for text
messages to be dicated by a microphone.

This patch adds a new key definition KEY_DICTATE and maps 0x0c/0x0d8
usage code to this new keycode. Additionally hid-debug is adjusted to
recognize this new usage code as well.
