From: Arnd Bergmann <arnd@xxxxxxxx> 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@xxxxxxxxx> Link: https://lore.kernel.org/oe-kbuild-all/202304251640.JClqTim9-lkp@xxxxxxxxx/ Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> --- 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. --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index 3647d21d688f..2bbb2988942d 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -6336,7 +6336,7 @@ amdgpu_dm_connector_late_register(struct drm_connector *connector) return 0; } -void amdgpu_dm_connector_funcs_force(struct drm_connector *connector) +static void amdgpu_dm_connector_funcs_force(struct drm_connector *connector) { struct amdgpu_dm_connector *aconnector = to_amdgpu_dm_connector(connector); struct dc_link *dc_link = aconnector->dc_link; -- 2.39.2
