The MIPI DCS specification demands that brightness values are sent in

be used for values that are between 9 and 16 bits wide.
Add new functions to properly handle 16-bit brightness in big endian,

drm/nouveau/fb/ga102: Replace zero-length array of trailing structs with flex-array
Zero-length arrays are deprecated[1] and are being replaced with
flexible array members in support of the ongoing efforts to tighten the
FORTIFY_SOURCE routines on memcpy(), correctly instrument array indexing
with UBSAN_BOUNDS, and to globally enable -fstrict-flex-arrays=3.
Replace zero-length array with flexible-array member.
This results in no differences in binary output.

drm/bridge: tc358767: Set default CLRSIPO count
The current CLRSIPO count is still marginal and does not work with high
DSI clock rates in burst mode. Increase it further to allow the DSI link
to work at up to 1Gbps lane speed. This returns the counts to defaults
as provided by datasheet.

Always free the console font when deinitializing the framebuffer
console. Subsequent framebuffer consoles will then use the default
font. Rely on userspace to load any user-configured font for these
consoles.
Commit ae1287865f53 ("fbcon: don't lose the console font across
generic->chip driver switch") was introduced to work around losing
the font during graphics-device handover. [1][2] It kept a dangling
pointer with the font data between loading the two consoles, which is
fairly adventurous hack. It also never covered cases when the other
consoles, such as VGA text mode, where involved.
The problem has meanwhile been solved in userspace. Systemd comes
with a udev rule that re-installs the configured font when a console
comes up. [3] So the kernel workaround can be removed.
This also removes one of the two special cases triggered by setting
FBINFO_MISC_FIRMWARE in an fbdev driver.
Tested during device handover from efifb and simpledrm to radeon. Udev
reloads the configured console font for the new driver's terminal.
