Subject: [PATCH] ALSA: usb-audio: Add quirk for LH Labs Geek Out HD Audio 1V5
Git-commit: 5f3d9e8161bb8cb23ab3b4678cd13f6e90a06186
Patch-mainline: v6.0-rc4
References: git-fixes

The USB DAC from LH Labs (2522:0007) seems requiring the same quirk as
Sony Walkman to set up the interface like UAC1; otherwise it gets the
constant errors "usb_set_interface failed (-71)".  This patch adds a
quirk entry for addressing the buggy behavior.
