[PATCH 00/14] drm: Remove infrastructure for user-space mode setting

[Thomas Zimmermann]

The old drivers for user-space mode setting have been removed in Linux
v6.3. No one has complained or requested their return. It is time to
remove these drivers' infrastructure from the DRM core.

The recent Linux v6.6 has been designated as long-term release, [1] so
any remaining users have a few more years to get a new graphics card. The
legacy devices continue to be supported via simpledrm. Merging proper
drivers with kernel mode setting is also an option.

Patches 1 to 7 fix a few trivial issues that have been forgotten during
the removal of the drivers.

Patches 8 and 9 remove the leagcy ioctl interfaces. One op is different
from the others, so it gets its own patch.

Patches 10 to 12 remove the legacy source code from DRM. With that gone
patch 13, the AGP code can be simplified as well. There used to be
a device file for user-space mode setting, /dev/agpgart, that is now
obsolete.

Patch 14 removes the option from Kconfig.
