--------------------------------

[ Upstream commit 632bac50544c0929ced9eed41e7d04c08adecbb0 ]

The framebuffer console stopped updating with commit f231af49
("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 039a72ce ("drm/i915/fbdev: Implement fb_dirty for intel
custom fb helper").

Fixes: f231af49 ("drm/fb-helper: Disconnect damage worker from update logic")
