Subject: [PATCH] ALSA: usb-audio: Configure Pioneer DJM-850 samplerate
Git-commit: 1a2a94a4392d5d1e5e25cc127573452f4c7fa9b8
Patch-mainline: v5.13-rc1
References: git-fixes
Send an `URB_CONTROL out` USB frame to the device to configure its
samplerate. This should be done before using the device for audio
streaming (capture or playback).
