[linux-dvb] I2C NAKs and fails to respond during init of TDA18211

Using the OM5776 eval board, and using the algorithm published
in the rev 1.1.0 datasheet, I find I am getting an I2C NAK,
which does not go away and requires a chip reset to restore
any I2C communication, after successfully writing EP4 (r06) in the
'image rejection cal pt I, wanted signal measurement' section
where registers are written back.
(NAK occurs on write to EP5)

Anyone with better experience ?

Thanks,
MikeW
