Merge branch 'drm-vc4-fixes' of git://github.com/anholt/linux into drm-fixes

Here are a few little VC4 fixes for 4.4 that I didn't get in to you
before the -next pull request.  I dropped the feature-ish one I'd
mentioned, and also droppped the one I saw you included in the last
-fixes pull request.

* 'drm-vc4-fixes' of git://github.com/anholt/linux:
  drm/vc4: Make sure that planes aren't scaled.
  drm/vc4: Fix some failure to track __iomem decorations on pointers.
  drm/vc4: checking for NULL instead of IS_ERR
  drm/vc4: fix itnull.cocci warnings
  drm/vc4: fix platform_no_drv_owner.cocci warnings
  drm/vc4: vc4_plane_duplicate_state() can be static
