Subject: [PATCH] ALSA: usb-audio: Add implicit fb support for Steinberg UR22
Git-commit: c9a867fd845171e6845e6fd665c423fa910083d8
Patch-mainline: v5.11-rc1
References: git-fixes
Steinberg UR22 (with USB ID 0499:1509) requires the implicit feedback
for the proper playback, otherwise it causes occasional cracks.
This patch adds the corresponding the quirk table entry with the
recently added generic implicit fb support.
