Have you checked that the drm_vblank_off in probe actually results in a
call to mxsfb_crtc_disable_vblank? From my reading of the core code,
this should be a no-op without a previous drm_vblank_on, so it would
not result in the desired masking before the IRQ is requested.
I must've missed the vblank->enabled check, but then, I am also not
getting any interrupts, so presumably they are already disabled after
the IP is reset.
