Some of the debugfs functions are stubbed out in these configurations,
so trying to build the .c file with the definition fails:

In file included from include/uapi/linux/posix_types.h:5,
from drivers/gpu/drm/i915/display/intel_pipe_crc.c:27:
drivers/gpu/drm/i915/display/intel_pipe_crc.c: At top level:

Stop trying to build them by making the Makefile entries conditional,
same as for the i915 driver.

Already fixed by commit 439987f6f471 ("drm/xe: don't build debugfs files
when CONFIG_DEBUG_FS=n") in drm-xe-next.

Maybe that needs to be picked up for -fixes?

I made sure that this still happens in linux-next today, but
it does not seem to contain 439987f6f471.

Looking at https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=2d5c7b7eb345249cb34d42cbc2b97b4c57ea944e
it seems we still don't have drm-xe-next branch in linux-next.

Stephen, could you please add it? Or do I have to do something on my end
before that? This is the branch:

https://gitlab.freedesktop.org/drm/xe/kernel drm-xe-next

thanks
