Subject: [PATCH AUTOSEL 5.4 3/5] drm/amdgpu: use dirty framebuffer helper

From: Hamza Mahfooz <[email protected]>

[ Upstream commit 66f99628eb24409cb8feb5061f78283c8b65f820 ]

Currently, we aren't handling DRM_IOCTL_MODE_DIRTYFB. So, use
drm_atomic_helper_dirtyfb() as the dirty callback in the amdgpu_fb_funcs
struct.
