Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.
I didn't convert drm_crtc_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.

Drivers shouldn't clobber the passed in addfb ioctl parameters.
i915 was doing just that. To prevent it from happening again,
pass the struct around as const, starting all the way from

commit is in your tree now so I might send that along once this is

drm/tegra: Changes for v4.4-rc1
Just a couple of minor fixes and cleanups for this cycle.
* tag 'drm/tegra/for-4.4-rc1' of git://anongit.freedesktop.org/tegra/linux:
drm/tegra: dc: Request/free syncpoint at init/exit
drm/tegra: fb: Remove gratuituous blank line
gpu: host1x: Fix MLOCK's debug info
|
|
syncpoints are resources provided by host1x and their lifetime is tied
to the host1x device. They are not properly reference counted either, so
removing the host1x device before any of its clients causes a use-after-
free error. Adding proper reference counting would be a major enterprise
so work around it for now by requesting and freeing the syncpoint at
init and exit time, respectively. The host1x device is guaranteed to be
around at this point.

Just one special case (since i915 lost its ums code, yay):
- radeon: Has slots for the old ums ioctls which don't have
DRM_UNLOCKED, but all filled with drm_invalid_op. So ok to drop it
everywhere.
Every other kms driver just has DRM_UNLOCKED for all their ioctls, as
they should.
v2: admgpu happened, include that one too. And i915 lost its UMS
support which means we can change all the i915 ioctls too.
v3: Rebased on top of new vmwgfx DX interface extensions.
v4: Rebase on top of render-node support in exynos.

With drivers supporting runtime pm it's generally not a good idea to
touch the hardware when it's off. Add an option to the commit_planes
helper to support this case.
Note that the helpers already add all planes on a crtc when a modeset
happens, hence plane updates will not be lost if drivers set this to
true.
v2: Check for NULL state->crtc before chasing the pointer. Also check
both old and new crtc if there's a switch. Finally just outright
disallow switching crtcs for a plane if the plane is in active use, on
most hardware that doesn't make sense.
v3: Since commit_planes(active_only = true) is for enabling things
only after all the crtc are on we should only look at the new crtc to
decide whether to call the plane hooks - if the current CRTC isn't on
then skip. If the old crtc (when moving a plane) went down then the
plane should have been disabled as part of the pipe shutdown work
already. For which there's currently no helper really unfortunately.
Also move the check for wether a plane gets a new CRTC assigned while
still in active use out of this patch.
v4: Rebase over exynos changes.

drm/tegra: Changes for v4.3-rc1
There are a bunch of non-critical fixes here that I've collected over
the past few months, but the biggest part is Tegra210 support, in the
DC, DSI and SOR/HDMI drivers.
Also this finally restores DPMS with atomic mode-setting, something
that has been broken since the conversion and which I had originally
expected to take far less longer to fix.

to use runtime PM in subsequent patches.

The DPAUX code paths already configure the pads in AUX mode, but there
