The audio variables in em28xx are a big mess: - many have misleading names - some are completely unnecessary - some duplicate in parts or even completely the meaning of others - some device features are described by combinations of multiple variables, which makes the code difficult to understand and allows inconsistencies So clean up the em28xx audio variables: - Patch 1 removes 3 unneeded audio variables. - Patch 2 replaces the variables "has_alsa_audio" and "has_audio_class" with a single enum variable describing the type of usb audio (no usb audio / audio class / vendor). - Patches 3+4 replace the variables "has_audio" and "ac97" of struct em28xx_audio_mode with a single enum variable describing the type of internal audio connection (none / ac97 / i2s). Variable "audio_mode" is finally removed together with the obsolete structs "em28xx_audio_mode" and "em28xx_ac97_mode". This simplifies the audio code a lot, making it much more self-explaining and easier to understand. It will hopefully reduce the risk of audio regression in the future.
