If drm_gem_handle_create() fails in vkms_gem_create(), then the
vkms_gem_object is freed twice: once when the reference is dropped by
drm_gem_object_put_unlocked(), and again by the extra calls to
drm_gem_object_release() and kfree().
Fix it by skipping the second release and free.
This bug was originally found in the vgem driver by syzkaller using
fault injection, but I noticed it's also present in the vkms driver.

When Daniel removed struct_mutex he didn't fix this call to the unlocked
variant which is required since we no longer use struct mutex.
This fixes a bunch of:

Split the csc matrix handling to ilk+ and icl+ functions.
This keeps the logic clear on what is loaded into which
CSC unit on the hardware.
We also fix the icl+ code to load the full->limited range
conversion matrix into the output CSC rather than the pipe
CSC which was used on earlier platforms. And we also turn
on the pipe CSC only when the ctm is present.

Let's start using the vfuncs to differentiate MG and Combo PLLs. The end
goal is to decouple the type of the PLL from the IDs since the latter
are likely to change from one platform to another. This also makes the

functions.

For compatibility reasons, we only care if the vGPU host provides
support for full-ppgtt. This is independent of the addressable memory
size, so remove the conflation of 48b from the capability name.

Using the new helpers introduced since we wrote that code, we can simplify
the code to retrieve the mixer ID significantly.
The new code will also allow us to deal nicely with endpoints that don't
have a reg property, as expected in the case where there's a single
endpoint for a given port.

Current driver sets the tile property only for DP MST connectors.
However there are some tiled displays where each SST connector
carries a single tile. So we need to attach this property object
for every connector and set it for every connector (DP SST and MST).
Plus since the tile information is obtained as a result of EDID
parsing, the best place to update tile property is where we update
edid property.
Also now we dont need to explicitly set this now for MST connectors.
This has been tested with xrandr --props and modetest and verified
that TILE property is exposed correctly.

When any other value than EDP_PSR_TP4_TIME_0US is set, TPS1 and TPS4
will be used to do the link training when exiting PSR1.
Happily the eDP panels tested so far was able to sync with source
even without HBR3/TPS4 support but let use the right training
pattern.
TPS4 support was added to PSR1 registers because HBR3/PSR
specification was not closed when ICL was freezed so if HBR3 was
supported by PSR, ICL would already be ready but it was not added to
specification so lets always disable TPS4.

In order to make it easier to bring up new platforms
without having to take care about all corner cases
that was previously taken care for previous platforms
we already use comparative INTEL_GEN statements.
Let's start doing the same with PCH.
The only caveats are:
- less-than comparisons need to be avoided or done with
attention and check > PCH_NONE as well.
- It is not necessarily a chronological order, but a matter
of south display compatibility/inheritance.

This exactly same approach was already used from gen9
to gen10 and from gen10 to gen11. Let's also use it
for gen11+.
Let's first assume that we inherit a similar platform
and than we apply the differences on top.
Different from the previous attempts this will be
done this time with coccinelle. We obviously need to
exclude some case that is really exclusive for gen11
like PCH, Firmware, and few others. Luckly this was
easy to filter by selecting the files we are touching
with coccinelle as exposed below:
spatch -sp_file gen11\+.cocci --in-place i915_perf.c \
intel_bios.c intel_cdclk.c intel_ddi.c \
intel_device_info.c intel_display.c intel_dpll_mgr.c \
