| Subject: ACPI: video: Add quirk for the Dell Vostro 3350 |
| |
| From: Hans de Goede <hdegoede@redhat.com> |
| |
| [ Upstream commit 9249c32ec9197e8d34fe5179c9e31668a205db04 ] |
| |
| The Dell Vostro 3350 ACPI video-bus device reports spurious |
| ACPI_VIDEO_NOTIFY_CYCLE events resulting in spurious KEY_SWITCHVIDEOMODE |
| events being reported to userspace (and causing trouble there). |
| |
| 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. |
