Re: [PATCH v2] [media] rtl2832: add support for slave ts pid filter

[Antti Palosaari <crope@xxxxxx>]

Hello
That patch does not apply anymore as new register access functions are 
now regmap ones. Also I don't see reason you set slave_ts value to false 
on rtl2832_init(). It just be just enough setting its value on 
rtl2832_slave_ts_ctrl().

regards
Antti
