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

Hi all,

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

ERROR: modpost: "device_is_dependent" [drivers/gpu/drm/drm_kms_helper.ko] undefined!

Caused by commit

  39d5b6a64ace ("drm/bridge: panel: Check device dependency before managing device link")

I have used the drm-misc-fixes tree from next-20231124 for today.

I've sent a new patch series to address the build failure.
It includes a new patch to export device_is_dependent and then
adds the offending commit.
