6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tony Lindgren <tony@xxxxxxxxxxx>
[ Upstream commit 632bac50544c0929ced9eed41e7d04c08adecbb0 ]
The framebuffer console stopped updating with commit f231af498c29
("drm/fb-helper: Disconnect damage worker from update logic").
Let's fix the issue by implementing fb_dirty similar to what was done
with commit 039a72ce7e57 ("drm/i915/fbdev: Implement fb_dirty for intel
custom fb helper").
Fixes: f231af498c29 ("drm/fb-helper: Disconnect damage worker from update logic")
