[PATCH AUTOSEL 6.1 4/9] ACPI: video: Add quirk for the Colorful X15 AT 23 Laptop

[Sasha Levin <sashal@kernel.org>]

From: Yuluo Qiu <qyl27@outlook.com>

[ Upstream commit 143176a46bdd3bfbe9ba2462bf94458e80d65ebf ]

The Colorful X15 AT 23 ACPI video-bus device report spurious
ACPI_VIDEO_NOTIFY_CYCLE events resulting in spurious KEY_SWITCHVIDEOMODE
events being reported to userspace (and causing trouble there) when
an external screen plugged in.

Add a quirk setting the report_key_events mask to
REPORT_BRIGHTNESS_KEY_EVENTS so that the ACPI_VIDEO_NOTIFY_CYCLE
events will be ignored, while still reporting brightness up/down
hotkey-presses to userspace normally.
