Revert "drm/fb-helper: Schedule deferred-I/O worker after writing to framebuffer"
This reverts commit 7f5cc4a3e5e4c5a38e5748defc952e45278f7a70.
Needed to restore the fbdev damage worker. There have been bug reports
about locking order [1] and incorrectly takens branches. [2] Restore
the damage worker until these problems have been resovled.
