[PATCH 0/3] Fixes and cleanup for DRM fbdev emulation and deferred I/O

[Javier Martinez Canillas <javierm@redhat.com>]

Hello,

This patch series contains two fixes and a cleanup for things that I noticed
while debugging a regression in the fbdev emulation for a DRM driver.

The first two patches are trivial and shoulnd't be controversial, the third
patch is less trivial, but it has been already reviewed by Thomas and I did
test it to make sure that works as expected. With it, I got rid of the WARN
that happened due a mutex used after it has been destroyed.

Best regards,
Javier
