[linux-dvb] Nexus-CA analogue module question

[Andrew de Quincey <adq_dvb@lidskialf.net>]

Hi, the av7110_init_anlog_module() function does this to detect an "analogue 
module":

 if (i2c_writereg(av7110, 0x80, 0x0, 0x80) != 1
     || i2c_writereg(av7110, 0x80, 0x0, 0) != 1)
  return -ENODEV;


However this fails on the nexus CA so the analogue system is never 
initialised. What is this actually talking doing?
