drm/i915: slow acpi_lid_open() causes flickering - V2
acpi_lid_open() could take up to 10ms on my computer. Some component is calling the drm GETCONNECTOR ioctl many times in a row. This results in flickering (for example, when starting a video). Fix it by assuming an always connected lid status. Signed-off-by: Thomas Meyer <thomas@m3y3r.de> Signed-off-by: Eric Anholt <eric@anholt.net>
