the MFD part (for example, wl1273_fm_read_reg/wl1273_fm_write_cmd/wl1273_fm_write_data). The logic that are related to control the radio (wl1273_fm_set_audio, wl1273_fm_set_volume, etc) are not related to access the device via the MFD bus. They should be at the media part of the driver, where they belong.
Those functions are being used by the audio driver.
Not sure if I understood your comments. Several media drivers have alsa drivers: saa7134, em28xx, cx231xx, etc. The audio drivers for them are also under /drivers/media, as it is not easy to de-couple audio and video/radio part on those devices. For bttv and some USB boards (that use snd-usb-audio), the audio part is at /sound, as the audio part on them are independent and don't need to share anything, as audio is provided by a completely independent group of registers.
I suggest to use the same logic for wl1273.
Cheers, Mauro.
