cc07057c7c video: fbdev: fix divide error in fbcon_switch 
This patch fixes the issue due to:

[   89.572883] divide_error: 0000 [#1] SMP KASAN PTI
[   89.572897] CPU: 3 PID: 16083 Comm: repro Not tainted 5.9.0-rc7.20200930.rc1.allarch-19-g3e32d0d.syzk #5
[   89.572902] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.5.1 01/01/2011
[   89.572934] RIP: 0010:cirrusfb_check_var+0x84/0x1260

The error happens when the pixels value is calculated before performing the sanity checks on bits_per_pixel.
A bits_per_pixel set to zero causes divide by zero error.

This patch moves the calculation after the sanity check.

37b254f111 drm/vc4: dsi: Only register our component once a DSI device is attached 
If the DSI driver is the last to probe, component_add will try to run all
the bind callbacks straight away and return the error code.

However, since we depend on a power domain, we're pretty much guaranteed to
be in that case on the BCM2711, and are just lucky on the previous SoCs
since the v3d also depends on that power domain and is further in the probe
order.

In that case, the DSI host will not stick around in the system: the DSI
bind callback will be executed, will not find any DSI device attached and
will return EPROBE_DEFER, and we will then remove the DSI host and ask to
be probed later on.

But since that host doesn't stick around, DSI devices like the RaspberryPi
touchscreen whose probe is not linked to the DSI host (unlike the usual DSI
devices that will be probed through the call to mipi_dsi_host_register)
cannot attach to the DSI host, and we thus end up in a situation where the
DSI host cannot probe because the panel hasn't probed yet, and the panel
cannot probe because the DSI host hasn't yet.

In order to break this cycle, let's wait until there's a DSI device that
attaches to the DSI host to register the component and allow to progress
further.

12767469ed drm: document that user-space should avoid parsing EDIDs 
User-space should avoid parsing EDIDs for metadata already exposed via
other KMS interfaces and properties. For instance, user-space should not
try to extract a list of modes from the EDID: the kernel might mutate
the mode list (because of link capabilities or quirks for instance).

Other metadata not exposed by KMS can be parsed by user-space. This
includes for instance monitor identification (make/model/serial) and
supported color-spaces.

v2: add short explanation why user-space shouldn't do this (Brian)
