Subject: RE: [Intel-gfx] [4.2-rc4] acpi|drm|i915: circular locking
dependency: acpi_video_get_backlight_type
Hi, Ville
Have you reported this to the owner of the backlight core?
This looks like a bug that the backlight core should handle.
What intel backlight driver and acpi backlight driver have done here are just invoking APIs provided by the backlight core.
So it is the duty of the backlight core to handle such kind of circular locking.
Thanks
