[PATCH v3 0/2] fbdev fixes

[Lukas Wunner <lukas@wunner.de>]

Respin of <cover.1446987413.git.lukas@wunner.de> with the following
changes as per feedback from Daniel and Ville:

- Order of the two patches is reversed.
- Patch 1 is rebased on Ville's async fbdev initialization changes.
- Patch 2 with reduced null pointer checks. (No need to check for
  fb or obj, now that ifbdev is destroyed on initialization failure.)

Caution: I'm using current_is_async() in patch 1 to avoid a deadlock,
which is currently not exported. I've submitted a patch to export it
with <cover.1447937831.git.lukas@wunner.de>.

Should the patch be rejected, it's possible to solve it by spliting
intel_fbdev_fini() in two parts as suggested by Ville, however I think
using current_is_async() is preferrable as it's simpler and less code.
