Subject: [PATCH] drm/amd/display: mark amdgpu_dm_connector_funcs_force static

From: Arnd Bergmann <arnd@...db.de>

A global function without a header prototype has made it into
linux-next during the merge window:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:6339:6: error: no previous prototype for 'amdgpu_dm_connector_funcs_force' [-Werror=missing-prototypes]

Mark the function static instead, as there are no other
callers outside this file.

Fixes: 0ba4a784a145 ("drm/amd/display: implement force function in amdgpu_dm_connector_funcs")
Reported-by: kernel test robot <lkp@...el.com>
Link: https://lore.kernel.org/oe-kbuild-all/202304251640.JClqTim9-lkp@intel.com/

This was previously reported by a bot for the drm-next tree but remains
broken in linux-next-20230428. Sending it out as I needed this fix
for my local builds.
