drm/bridge: panel: Introduce drmm_panel_bridge_add

Unlike what can be found for other entities, there's no DRM-managed
function to create a panel_bridge instance from a panel.

Let's introduce one.

drm/connector: Consolidate Connector Initialization

We're going to add a DRM-managed connector initialization function.
Since we'll need both the with and without the DDC pointer, having a
single function that takes an optional pointer is easier to maintain.

Let's create a static function that will back both existing variants,
and will be reused by the DRM-managed variant.

drm/connector: Clarify when drm_connector_unregister is needed

The current documentation for drm_connector_unregister() mentions that
it's needed for connectors that have been registered through
drm_dev_register().

However, this was a typo and was meant to be drm_connector_register(),
which only applies to connectors registered after drm_dev_register() has
been called.

In addition, it was also mentioning that connectors are unregistered
automatically when drm_dev_unregister() is called. This part is a bit
misleading, since it might make it appear that
drm_connector_unregister() applies either to all connectors, or none of
them.

After discussing it with Daniel, it appears that we always need to call
drm_connector_unregister() on connectors that have been registered with
drm_connector_register(), but only those.

drm_connector_init() already mentions that it only needs
drm_connector_cleanup(), so let's clarify the drm_connector_register()
and drm_connector_unregister() documentation to point at each other, and
remove the misleading part about drm_dev_unregister().

However, we might want to separate the structure creation and the encoder

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

Linux 5.19-rc6

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.

* merge 'hot-fixes' branch:
  ida: don't use BUG_ON() for debugging
  drm/aperture: Run fbdev removal before internal helpers
  ptrace: fix clearing of JOBCTL_TRACED in ptrace_unfreeze_traced()

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).

ptrace: fix clearing of JOBCTL_TRACED in ptrace_unfreeze_traced()

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

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.

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,
