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

Hi all,

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

Ups, had not seen this one coming.
We are in the process of removing the drivers in drivers/video/fbdev/omap2/omapfb/
and decided to introduce the new drivers early to get them out of a
longer patch series.

Should we have a config dependency to not allow the old fbdev omap
when the drm omap driver is enabled? I think that would take care of
all this.

Or too annoying for development?

Also note that fbdev is in drm-misc now, so we should be able to fix
this all without cross-tree conflicts.

Oops :-(

The new drivers were initially part of a patch series that removed the
duplicated drivers. The new drivers then got fast-tracked, and I didn't
notice this issue.

Note that drivers/video/fbdev/omap2/omapfb/ will stay, it's
drivers/gpu/drm/omapdrm/displays/ that is being removed. FB_OMAP2
already depends on DRM_OMAP = n, I propose doing something similar at
the level of the individual display drivers.

I've just posted "[PATCH 0/2] Fix module name clash with omapdrm and DRM
panel modules" that should solve this issue.

Once again, I apologize. I have sent a patch[0]  which I hope will fix this issue.
When I ran "make htmldocs" locally, I didn't see this warning. I'm not sure if it's because my method was incorrect.

The fix is here：

Hope that a Maintainer can review and apply it.

I tried picking it up into the drm-misc-next-fixes branch, but I could
not do it: the offending commit is present in drm-misc-next-2025-07-17,
while drm-misc-next-fixes is based on drm-misc-next-2025-07-10.
