Subject: [PATCH 02/21] drivers: video: backlight: Disable backlight
|
|
notification events.
|
|
|
|
We don't want to generate udev events for brightness changes on Steam Deck,
|
|
as some games like Celeste will re-enumerate controller devices in response
|
|
to this event.
|
|
|
|
Patch from Sam Lantinga.
|
|
|
|
(cherry picked from commit 85da5a5f7b69f22f960776cde3bf5862f3613363)
