drm/amd/powerplay: wrong control mode cause the fan spins faster unnecessarily
drm/amd/powerplay: fix memory leak of hardcoded pptable
drm/amdgpu:add fw-vram-usage for atomfirmware
drm/radeon: fix atombios on big endian
drm/ttm:fix memory leak due to individualize
drm/amdgpu: fix error handling in amdgpu_bo_do_create
drm/ttm: once more fix ttm_buffer_object_transfer
