Subject: [PATCH 03/13] media: i2c: ds90ub960: Fix use of non-existing
registers on UB9702
UB9702 doesn't have the registers for SP and EQ. Adjust the code in
ub960_rxport_wait_locks() to not use those registers for UB9702. As
these values are only used for a debug print here, there's no functional
change.
