RFC PATCH 1/1 drivers/media/video/bt8xx/: possible cleanups
This patch contains the following possible cleanups:
- remove the following unused global functions:
- bttv-if.c: bttv_get_cardinfo()
- bttv-if.c: bttv_get_id()
- bttv-if.c: bttv_get_gpio_queue()
- bttv-if.c: bttv_i2c_call()
- remove the following unused EXPORT_SYMBOL's:
- bttv-gpio.c: bttv_sub_bus_type
- bttv-gpio.c: bttv_gpio_inout
- bttv-gpio.c: bttv_gpio_read
- bttv-gpio.c: bttv_gpio_write
- bttv-gpio.c: bttv_gpio_bits
