[PATCH 07/14] ALSA: usb-audio: scarlett2: Rename buttons/interrupts/vol
Geoffrey D. Bennett
g at b4.vu
Sun Jun 20 18:46:36 CEST 2021
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
