    V4L/DVB (7749): cx88: fix tuner setup · 4bf1226a
    Mauro Carvalho Chehab authored
    Tuner setup were happening during i2c attach callback. This means that it would
    happen on two conditions:
    
    	1) if tuner module weren't load, it will happen at request_module("tuner");
    
    	2) if tuner is not compiled as a module, or it is already loaded
    	   (for example, on setups with more than one tuner), it will happen
    	   when cx88 registers I2C bus.
    
    Due to that, if tuner were loaded, tuner setup will happen _before_ reading
    the proper values at tuner eeprom. Since set_addr refuses to change for a tuner
    that were previously defined (except if the tuner_addr is set), this were making
    eeprom tuner detection useless.
    
    This patch removes tuner type setup from cx88-i2c, moving it to the proper
    place, after taking eeprom into account.
