[PATCH 3.18 04/10] ALSA: usb-audio: Apply sample rate quirk to Sennheiser headset

From: Greg Kroah-Hartman
Date: Tue Aug 22 2017 - 15:35:46 EST


3.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@xxxxxxx>

commit a8e800fe0f68bc28ce309914f47e432742b865ed upstream.

A Senheisser headset requires the typical sample-rate quirk for
avoiding spurious errors from inquiring the current sample rate like:
usb 1-1: 2:1: cannot get freq at ep 0x4
usb 1-1: 3:1: cannot get freq at ep 0x83

The USB ID 1395:740a has to be added to the entries in
snd_usb_get_sample_rate_quirk().
