Subject: [PATCH 10/13] media: i2c: ds90ub960: Reduce sleep in
 ub960_rxport_wait_locks()

We currently sleep for 50 ms at the end of each iteration in
ub960_rxport_wait_locks(). This feels a bit excessive, especially as we
always do at least two loops, so there's always at least one sleep, even
if we already have a stable lock.

Change the sleep to 10 ms.
