Subject: [PATCH AUTOSEL 6.9 43/44] input: Add support for "Do Not Disturb"

From: Aseda Aboagye <aaboagye@...omium.org>

[ Upstream commit 22d6d060ac77955291deb43efc2f3f4f9632c6cb ]

HUTRR94 added support for a new usage titled "System Do Not Disturb"
which toggles a system-wide Do Not Disturb setting. This commit simply
adds a new event code for the usage.
