[ Upstream commit 3306ba4b60b2f3d9ac6bddc587a4d702e1ba2224 ]
Three functions in the amdgpu display driver cause -Wmissing-prototype warnings:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:1858:6: error: no previous prototype for 'is_timing_changed' [-Werror=missing-prototypes]
is_timing_changed() is actually meant to be a global symbol, but needs a proper name and prototype.
