The bttv card database is quite large and the data structure used to store it wasn't very efficient. Most of the field are only used at card initialization time so it doesn't matter if they aren't efficient to access. Overall the changes reduce code size by 60 bytes in ia32. The data size is decreased by 5024 byes. It is probably even more for 64-bit kernels. Move the fields in the struct around to be sorted from largest to smallest. This saves on padding space used for alignment. Get rid of the unused digital_mode field. Leave the setting as a comment in the few cards entries that set it, in case someone ever writes the code. Get rid of the unused audio_inputs field. Leave the values in the card entries in case someone ever writes code that might use it. Get ride of the unused radio_addr field. No card entries even set it to anything interesting so it's not left as comments. All the code that used it was removed in commit v2.6.14-3466-g291d1d7 from Nov 8th 2005. Reduce video_inputs to u8 as no card has more than 255 inputs (the most is 16). Change tuner_addr to u8. I2C addresses are only seven bits and 255 means ADDR_UNSET, so everything fits. Make has_radio a one bit flag. Make the pll setting a two bit field. Reduce svhs to four bits as no card has an s-video input above 9. Change the value for no s-video input from UNSET (which is -1U and out of range of four bits) to NO_SVHS (which is now 15).
