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
