Regarding this patch in particular, there is still missing an acked-by
from a "bridge" maintainer. Also it could be nice to wait for the
reviewed-by from Jiry as it knows well this sii driver and sent recently
good patches on it (already merged).
With that, Benjamin or I (or a bridge maintainer) can push this patch +
the serie named "drm/bridge: sii902x: fix audio mclk management" as I
think it is better to push this serie *before* this patch.
Thanks,
Philippe :-)
