I tested this series, and then tested this series + "[PATCH v1 1/1] 
media: i2c: ds90ub960: Remove of_node assignment". I didn't see anything 
amiss in either case.

Tested-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>

I assume the ds90ub960 patch is the "single driver that does this and 
fix was sent today"? If so, I think that patch could have been included 
in this series as well, there's hardly a chance of conflicts with the 
one liner. And if applied separately, we probably need to apply the 
ub960 patch one kernel version later than this series.
