Subject: drm/bochs: Remove sending of vblank event
X-Git-Tag: v5.15~303^2~28^2~3597
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ebe162cdebe0e93887432d7daad1361dbc9ce7bb;p=platform%2Fkernel%2Flinux-starfive.git

drm/bochs: Remove sending of vblank event

The atomic helpers automatically send out fake VBLANK events if no
vblanking has been initialized. Remove the sending code from the
driver.

v4:
	* separate commit from core vblank changes
