ALSA: usb-audio: scarlett2: Rename buttons/interrupts/vol
To match the vendor's terminology, change #defines, identifiers, and comments: - mute/dim/hardware buttons are now called dim/mute - mixer status/interrupt is now notify - vol is now monitor Signed-off-by: Geoffrey D. Bennett <g@b4.vu> Link: https://lore.kernel.org/r/20210620164636.GA9199@m.b4.vu Signed-off-by: Takashi Iwai <tiwai@suse.de>
