From 16f1f838442dc6430d32d51ddda347b8421ec34b Mon Sep 17 00:00:00 2001 From: Takashi Iwai tiwai@suse.de Date: Wed, 4 Jan 2023 16:09:44 +0100 Subject: [PATCH] Revert "ALSA: usb-audio: Drop superfluous interface setup at parsing"

This reverts commit ac5e2fb425e1121ceef2b9d1b3ffccc195d55707.

The commit caused a regression on Behringer UMC404HD (and likely others). As the change was meant only as a minor optimization, it's better to revert it to address the regression.
