[PATCH v2 0/3] drm/gma500: Fix 2 locking related WARNs + IRQ handling

[Hans de Goede]

Hi All,

I have been testing the gma500 code on a Packard Bell Dot SC (Intel Atom
N2600, cedarview) laptop because I'm working on aligning the gma500
backlight code with the changes done to other drivers in the recent
backlight refactoring.

During the testing I noticed dmesg filling with a WARN_ON constantly
triggering as well as gnome-shell hanging after a suspend-resume cycle.

This series fixes 2 locking WARNs as well as vblank IRQs no longer
getting processed after a suspend-resume.

Changes in v2:
- Drop "drm/gma500: Fix crtc_vblank reference leak when userspace queues multiple events"
- Add "drm/gma500: Fix (vblank) IRQs not working after suspend/resume"

Regards,

Hans
