Subject: [PATCH] ALSA: usb-audio: fix Corsair Virtuoso mixer label collision
Git-commit: 7d8d3c377cc9731c3924f807c7769177ca3f0865
Patch-mainline: v5.6-rc1
References: bsc#1111666

The Corsair Virtuoso RGB Wireless is a USB headset with a mic and a
sidetone feature. Label its mixer appropriately instead of all
"Headset", so that applications such as Pulseaudio don't just move
the sidetone control when they intend the main Headset control.
