92915da647 drm/rockchip: vop: fix crtc size in plane check
If the geometry of a crtc is changing in an atomic update then we must
validate the plane size against the new state of the crtc and not the
current size, otherwise if the crtc size is increasing the plane will be
cropped at the previous size and will not fill the screen.

Bunch of small fixupes all over. Plus a dma-buf patch that Sumit asked me
to cherry-pick since that's the only one he had in his tree.

There's a sparse issue outstanding in the color mgr stuff, but Lionel is
still working on something that actually appeases sparse.

The function this used changed in
    092c96a8ab
    drm/radeon: fix dp link rate selection (v2)

However for MST we should just always train to the
max link/rate. Though we probably need to limit this
for future hw, in theory radeon won't support it.

This fixes my 30" monitor with MST enabled.

18b862dcd5 dma-buf, drm, ion: Propagate error code from dma_buf_start_cpu_access()
Drivers, especially i915.ko, can fail during the initial migration of a
dma-buf for CPU access. However, the error code from the driver was not
being propagated back to ioctl and so userspace was blissfully ignorant
of the failure. Rendering corruption ensues.

Whilst fixing the ioctl to return the error code from
dma_buf_start_cpu_access(), also do the same for
dma_buf_end_cpu_access().  For most drivers, dma_buf_end_cpu_access()
cannot fail. i915.ko however, as most drivers would, wants to avoid being
uninterruptible (as would be required to guarrantee no failure when
flushing the buffer to the device). As userspace already has to handle
errors from the SYNC_IOCTL, take advantage of this to be able to restart
the syscall across signals.

This fixes a coherency issue for i915.ko as well as reducing the
uninterruptible hold upon its BKL, the struct_mutex.

Fixes commit c11e391da2

e608787779 drm/sti: restore mode_fixup callback
Commit 8a2fa38fdd removed the mode_fixup because it was empty,
but 652353e6e5 modified it to call drm_mode_set_crtcinfo()
instead.

Both commits are correct, but the merge of the two kept the nonempty
version without the reference to it, as shown by the gcc warning:

 drm/sti/sti_crtc.c:54:13: error: 'sti_crtc_mode_fixup' defined but not used

This restores the callback pointer to fix the merge.

drm/tegra: Changes for v4.6-rc1

Only two cleanups this time around. One fixes reference counting of
device tree nodes, the other changes the return value of a function
from an unsigned int to an int to reflect that it will return error
codes.

3cf8bb1ad1 drm/radeon: fix indentation.
I hate doing this but it hurts my eyes to go over code that does not
comply with indentation rules. Only thing that is not only space change
is in atom.c all other files are space indentation issues.

341917fe2b gpu: host1x: Use a signed return type for do_relocs()
The return type "unsigned int" was used by the do_relocs() function
despite the fact that it will eventually return a negative error code.
Use a signed integer instead to accomodate for error codes.

This issue was detected by using the Coccinelle software.

93ec302976 gpu: host1x: bus: Add missing of_node_put()
for_each_child_of_node() performs an of_node_get() on each iteration, so
to break out of the loop an of_node_put() is required.

Found using Coccinelle. The semantic patch used for this is as follows:

// <smpl>

expression e;
local idexpression n;
@@

 for_each_child_of_node(..., n) {
   ... when != of_node_put(n)

86d65b7e7a nouveau: fix nv40_perfctr_next() cleanup regression
gcc-6 warns about code in the nouveau driver that is obviously silly:

drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c: In function 'nv40_perfctr_next':
drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c:62:19: warning: self-comparison always evaluats to false [-Wtautological-compare]
  if (pm->sequence != pm->sequence) {

The behavior was accidentally introduced in a patch described as "This is
purely preparation for upcoming commits, there should be no code changes here.".
As far as I can tell, that was true for the rest of that patch except for
this one function, which has been changed to a NOP.

This patch restores the original behavior.
