cde3d37b19 drm: Remove unnecessary include statements for drm_crtc_helper.h 
Several DRM core and helper source files include drm_crtc_helper.h
without needing it or only to get its transitive include statements;
leading to unnecessary compile-time dependencies.

Directly include required headers and drop drm_crtc_helper.h where
possible. The header file, drm_fixed.h, includes <linux/kernel.h>
for lower_32_bits().

v2:
	* include drm_crtc_helper.h in drm_crtc_helper.c (Sam)

54d47689c6 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.

12d5796d55 Revert "fbcon: don't lose the console font across generic->chip driver switch" 
This reverts commit ae1287865f.

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 ae1287865f ("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.
