Subject[PATCH 4.9 09/27] ALSA: usb-audio: Apply sample rate quirk to Sennheiser headset
Message-ID<uhn2b-6Mv-59@gated-at.bofh.it>
4.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Takashi Iwai <tiwai@suse.de>

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().
