ALSA: scarlett2: Add support for software-controllable input gain
Some devices in the Scarlett Gen 4 series have support for software-controllable input gain. Along with this comes a channel select option, an auto-gain feature, "safe" mode, and linking two channels into a stereo pair. Mark the new scarlett2_notify_input_*() functions with __always_unused until they get used when the Gen 4 notification callback function arrays are added. Signed-off-by: Geoffrey D. Bennett <g@b4.vu> Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://lore.kernel.org/r/fc39e80bb39863dd1579d342097203942b4f3034.1703612638.git.g@b4.vu
