drm/crtc: Introduce drmm_crtc_init_with_planes
The DRM-managed function to register a CRTC is
drmm_crtc_alloc_with_planes(), which will allocate the underlying
structure and initialisation the CRTC.
However, we might want to separate the structure creation and the CRTC
initialisation, for example if the structure is shared across multiple
DRM entities, for example an encoder and a connector.
Let's create an helper to only initialise a CRTC that would be passed as
an argument.

drm/mipi-dsi: Detach devices when removing the host
Whenever the MIPI-DSI host is unregistered, the code of
mipi_dsi_host_unregister() loops over every device currently found on that
bus and will unregister it.
However, it doesn't detach it from the bus first, which leads to all kind
of resource leaks if the host wants to perform some clean up whenever a
device is detached.

Merge branch 'hot-fixes' (fixes for rc6)
This is a collection of three fixes for small annoyances.
Two of these are already pending in other trees, but I really don't want
to release another -rc with these issues pending, so I picked up the
patches for these things directly. We'll end up with duplicate commits
eventually, I prefer that over having these issues pending.
The third one is just me getting rid of another BUG_ON() just because it
was reported and I dislike those things so much.

ida: don't use BUG_ON() for debugging
This is another old BUG_ON() that just shouldn't exist (see also commit
a382f8fee42c: "signal handling: don't use BUG_ON() for debugging").
In fact, as Matthew Wilcox points out, this condition shouldn't really
even result in a warning, since a negative id allocation result is just
a normal allocation failure:
"I wonder if we should even warn here -- sure, the caller is trying to
free something that wasn't allocated, but we don't warn for
kfree(NULL)"
and goes on to point out how that current error check is only causing
people to unnecessarily do their own index range checking before freeing
it.
This was noted by Itay Iellin, because the bluetooth HCI socket cookie
code does *not* do that range checking, and ends up just freeing the
error case too, triggering the BUG_ON().
The HCI code requires CAP_NET_RAW, and seems to just result in an ugly
splat, but there really is no reason to BUG_ON() here, and we have
generally striven for allocation models where it's always ok to just do
free(alloc());
even if the allocation were to fail for some random reason (usually
obviously that "random" reason being some resource limit).

drm/fourcc: Add DRM_FORMAT_D[1248]
As Rn covers single-channel formats with a direct relationship between
channel value and brightness, and Cn can be any colors, there are
currently no fourcc codes to describe single-channel formats with an
inverse relationship between channel value and brightness.
Introduce fourcc codes for a single-channel frame buffer format with
two, four, sixteen, or 256 brightness ("darkness") levels, where there
is an inverse relationship between channel value and brightness.
As the number of bits per pixel may be less than eight, some of these
formats rely on proper block handling for the calculation of bits per
pixel and pitch.
The fill order (the order in which multiple pixels are packed in a byte)
is the same order as used for grayscale (2, 4, and 16 levels) images in
the PNG specification, Version 1.2.
This order is also the recommended and default order (FillOrder = 1) for
bilevel and grayscale (16 levels) images in the TIFF 6.0 Specification,
and is also used for monochrome images in the PBM file format,
monochrome Linux frame buffer logos, and BDF and PSF (Linux kernel) font

gpu: host1x: Initialize syncval in channel_submit()
During the refactoring of channel_submit(), assignment of syncval was
moved but it is also used in channel_submit(). Add this assignment back
to channel_submit() as well.

drm/msm/dpu: Fix for non-visible planes
Fixes `kms_cursor_crc --run-subtest cursor-offscreen`.. when the cursor
moves offscreen the plane becomes non-visible, so we need to skip over
it in crtc atomic test and mixer setup.

drm/tegra: Include DMA API header where used
Even though the IOVA API never actually needed it, iova.h is still
carrying an include of dma-mapping.h, now solely for the sake of not
breaking tegra-drm. Fix that properly.

drm/tegra: Fix vmapping of prime buffers
The code assumes that Tegra GEM is permanently vmapped, which is not
true for the scattered buffers. After converting Tegra video decoder
driver to V4L API, we're now getting a BUG_ON from dma-buf core on playing
video using libvdpau-tegra on T30+ because tegra_gem_prime_vmap() sets
vaddr to NULL. Older pre-V4L video decoder driver wasn't vmapping dma-bufs.
Fix it by actually vmapping the exported GEMs.
