[0/3] drm/gma500: Fix 2 locking related WARN_ON oopses

Message

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.

This series consists of 3 small non backlight fixes,
2 of which fix WARN_ON oopses/backtraces.

Regards,

Hans
