-Subject: [PATCH] drm/vc4: Fix vblank timestamping for firmwarekms.
-
-The core doesn't expect a false return from the scanoutpos function in
-normal usage, so we were doing the precise vblank timestamping path
-and thus "immediate" vblank disables (even though firmwarekms can't
-actually disable vblanks interrupts, sigh), and the kernel would get
-confused when getting timestamp info when also turning vblanks back
-on.
