drm/vblank: Use abs64(diff_ns) for s64 diff_ns instead of abs(diff_ns) Use of abs() wrongly wrapped diff_ns to 32 bit, which gives a 1/4000 probability of a missed vblank increment at each vblank irq reenable if the kms driver doesn't support high precision vblank timestamping. Not a big deal in practice, but let's make it nice. Signed-off-by: Mario Kleiner <mario.kleiner@tuebingen.mpg.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
