The file amdgpu_dm_plane.c missed the header amdgpu_dm_plane.h, which resulted on the following warning: drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:1046:5: warning: no previous prototype for 'fill_dc_scaling_info' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:1222:6: warning: no previous prototype for 'handle_cursor_update' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:152:6: warning: no previous prototype for 'modifier_has_dcc' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:1576:5: warning: no previous prototype for 'amdgpu_dm_plane_init' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:157:10: warning: no previous prototype for 'modifier_gfx9_swizzle_mode' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:752:5: warning: no previous prototype for 'fill_plane_buffer_attributes' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:83:31: warning: no previous prototype for 'amd_get_format_info' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:88:6: warning: no previous prototype for 'fill_blending_from_plane_state' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:992:5: warning: no previous prototype for 'dm_plane_helper_check_state' [-Wmissing-prototypes] Therefore, include the missing header on the file and turn global functions that are not used outside of the file into static functions.
