Subject: [PATCH] [media] tda10023: fix wrong register assignment


Register INTP1 (0x12) Bit POCLKP (bit 0) sets the output clock polarity 
of tda10023 . However, the driver tries to set the parallel output mode 
in this register which is not correct.

Parallel output mode is set on register INTP2 (0x20) INTPSEL (bit 1/0) .

Drivers affected by this patch are the anysee devices.
