[PATCH 7.0 34/42] ALSA: usb-audio: apply quirk for MOONDROP JU Jiu

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

7.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Cryolitia PukNgae <cryolitia.pukngae@linux.dev>

commit 4513d3e0bbc0585b86ccf2631902593ff97e88f5 upstream.

It(ID 31b2:0111 JU Jiu) reports a MIN value -12800 for volume control, but
will mute when setting it less than -10880.

Thanks to my girlfriend Kagura for reporting this issue.
