drm/mgag200: Delete an unnecessary check before drm_gem_object_unreference_unlocked()

2016-07-22T15:23:39+00:00

The drm_gem_object_unreference_unlocked() function tests whether
its argument is NULL and then returns immediately.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

Merge remote-tracking branch 'airlied/drm-next' into topic/drm-misc

2016-07-19T07:27:29+00:00

Backmerge drm-next to be able to apply Chris' connector_unregister_all
cleanup (need latest i915 and sun4i state for that).

Also there's a trivial conflict in ttm_bo.c that git rerere fails to
remember.

drm/mgag200: make fbdev support really optional

2016-07-18T07:11:34+00:00

Currently enabling MGA G200 DRM support automatically pulls in
fbdev dependency. However this dep is unnecessary since
DRM core already handles this for us (DRM_FBDEV_EMULATION).

drm/ttm: remove dummy bo_move implementations

2016-07-07T18:54:34+00:00

It's pointless to only call the default implementation.

Merge tag 'topic/drm-misc-2016-06-07' of git://anongit.freedesktop.org/drm-intel into drm-next

2016-06-09T01:19:28+00:00

As promised, piles of prep work all around:
- drm_atomic_state rework, prep for nonblocking commit helpers
- fence patches from Gustavo and Christian to prep for atomic fences and
  some cool work in ttm/amdgpu from Christian
- drm event prep for both nonblocking commit and atomic fences
- Gustavo seems on a crusade against the non-kms-native version of the
  vblank functions.
- prep work from Boris to nuke all the silly ->best_encoder
  implementations we have (we really only need that for truly dynamic
  cases like dvi-i vs dvi-d or dp mst selecting the right transcoder on
  intel)
- prep work from Laurent to rework the format handling functions
- and few small things all over

drm/core: Change declaration for gamma_set.

2016-06-07T13:30:09+00:00

Change return value to int to propagate errors from gamma_set,
and remove start parameter. Updates always use the full size,
and some drivers even ignore the start parameter altogether.

This is needed for atomic drivers, where an atomic commit can
fail with -EINTR or -ENOMEM and should be restarted. This is already
and issue for drm_atomic_helper_legacy_set_gamma, which this patch
fixes up.

Changes since v1:
- Fix compiler warning. (Emil)
- Fix commit message (Daniel)

drm: Remove unused drm_device from drm_gem_object_lookup()

2016-05-17T06:47:30+00:00

drm_gem_object_lookup() has never required the drm_device for its file
local translation of the user handle to the GEM object. Let's remove the
