Subject: [PATCH AUTOSEL 5.14 006/252] drm/omap: Follow implicit fencing in prepare_fb

From: Daniel Vetter <daniel.vetter@...ll.ch>

[ Upstream commit 942d8344d5f14b9ea2ae43756f319b9f44216ba4 ]

I guess no one ever tried running omap together with lima or panfrost,
not even sure that's possible. Anyway for consistency, fix this.
