[ 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.
