From ac5e2fb425e1121ceef2b9d1b3ffccc195d55707 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 31 Aug 2022 15:00:21 +0200 Subject: ALSA: usb-audio: Drop superfluous interface setup at parsing We reset each interface that is being parsed for each stream, but this is superfluous and even can lead to spurious errors. Since the interface is set up properly at opening the endpoint for each actual stream operation, let's drop the superfluous one.
