However, the only values it could ever be are 0 and UNSET. Having a tuner on an input other than 0 didn't work and was never used. There is also a "tuner_type" field that can be set to TUNER_ABSENT to indicate no tuner, which makes "tuner = UNSET" redundant. In many cases, tuner_type was set to UNSET when there was no tuner, which isn't quite correct. tuner_type == UNSET is supposed to mean the tuner type isn't yet known. So, I changed cards where "tuner == UNSET" to always have tuner_type of TUNER_ABSENT. At this point the tuner field is redundant, so I deleted it. I have the card setup code set the card's tuner_type (not the card type's tuner_type!) to TUNER_ABSENT if it hasn't yet been set at the end of the setup code. Various places that check if the card has a tuner will now look for this instead of checking the card type's "tuner" field. Also autoload the tuner module before issuing the TUNER_SET_TYPE_ADDR I2C client call instead of after issuing it. Overall, on ia32 this decreases compiled code size by about 24 bytes and reduces the data size by 640 bytes.
