fb84efa28a drm/aperture: Run fbdev removal before internal helpers 
Always run fbdev removal first to remove simpledrm via
sysfb_disable(). This clears the internal state. The later call
to drm_aperture_detach_drivers() then does nothing. Otherwise,
with drm_aperture_detach_drivers() running first, the call to
sysfb_disable() uses inconsistent state.

Example backtrace show below:

e60c435484 drm/bridge: imx: Add LDB support for i.MX8qm 
This patch adds a drm bridge driver for i.MX8qm LVDS display bridge(LDB)
which is officially named as pixel mapper.  The LDB has two channels.
Each of them supports up to 30bpp parallel input color format and can
map the input to VESA or JEIDA standards.  The two channels can be used
simultaneously, either in dual mode or split mode.  In dual mode, the
two channels output identical data.  In split mode, channel0 outputs
odd pixels and channel1 outputs even pixels.  This patch supports the
LDB single mode and split mode.

Each of them supports up to 24bpp parallel input color format and can map

3f49f7591e drm/bridge: anx7625: Zero error variable when panel bridge not present 
While parsing the DT, the anx7625 driver checks for the presence of a
panel bridge on endpoint 1. If it is missing, pdata->panel_bridge stores
the error pointer and the function returns successfully without first
cleaning that variable. This is an issue since other functions later
check for the presence of a panel bridge by testing the trueness of that
variable.

In order to ensure proper behavior, zero out pdata->panel_bridge before
returning when no panel bridge is found.

fc67615f4e drm/edid: fix CTA data block collection size for CTA version 3 
The CTA Data Block Collection is valid only for CTA extension version
3. In versions 1 and 2, it is a reserved block, which we ignore.

The DTD start offset (byte 2, or d in CTA-861 spec), which determines
the CTA Data Block Collection size, is specified slightly differently
for different versions:

Version 1:
    d = offset for the byte following the reserved data block. If no
    data is provided in the reserved data block, then d=4. If no DTDs
    are provided, then d=0

Version 2:
    d = offset for the byte following the reserved data block. If no
    data is provided in the reserved data block, then d=4. If d=0, then
    no detailed timing descriptors are provided, and no data is provided
    in the reserved data block.

Version 3:
    d = offset for the byte following the data block collection. If no
    data is provided in the data block collection, then d=4. If d=0,
    then no detailed timing descriptors are provided, and no data is
    provided in the data block collection.

Ever since commit 9e50b9d55e ("drm: edid: Add some bounds checking"),
we've interpreted 0 to mean there are no DTDs but it's all Data
Blocks. Per the spec, Data Blocks are only valid for version 3, where we
should interpret 0 to mean there are no data blocks.

Follow the spec (and hope the EDIDs follow it too).

Currently, the memory to the composition frame is being allocated using
the kzmalloc. This comes with the limitation of maximum size of one
page size(which in the x86_64 is 4Kb and 4MB for default and hugepage
respectively).

Somes test of igt (e.g. kms_plane@pixel-format) uses more than 4MB when
testing some pixel formats like ARGB16161616 and the following error were
showing up when running kms_plane@plane-panning-bottom-right*:

[drm:vkms_composer_worker [vkms]] *ERROR* Cannot allocate memory for
output frame.

This problem is addessed by allocating the memory using kvzalloc that
