Subject: ALSA: usb-audio: Apply sample rate quirk to Sennheiser headset

From: Takashi Iwai <[email protected]>

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().
