Subject: linux-next: build failure after merge of the drm-misc tree

Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/xe/xe_guc_submit.c: In function 'simple_error_capture':
drivers/gpu/drm/xe/xe_guc_submit.c:814:48: error: passing argument 1 of 'drm_err_printer' from incompatible pointer type [-Werror=incompatible-pointer-types]

Caused by commit

  5e0c04c8c40b ("drm/print: make drm_err_printer() device specific by using drm_err()")

I have used the drm-misc tree from next-20240209 again today.
