[PATCH 0/9] drm: Fix includes of <linux/export.h>

[PATCH 0/9] drm: Fix includes of <linux/export.h>

[Thomas Zimmermann]

Some source files in DRM do not include <linux/export.h> properly;
others do when they don't have to. The build scripts now warn about
these cases.

This series fixes DRM core and helpers. There are a few more warnings
in drivers.

Commit 7d95680d64ac ("scripts/misc-check: check unnecessary #include
<linux/export.h> when W=1") and commit a934a57a42f6 ("scripts/misc-check:
check missing #include <linux/export.h> when W=1") added these new
warnings in v6.16-rc1.

Thomas Zimmermann (9):
  drm: Do not include <linux/export.h>
