Subject: [PATCH 3.19 049/175] ALSA: usb: Fix support for Denon DA-300USB DAC (ID 154e:1003)

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

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

From: Frank C Guenther <bugzilla.frnkcg@...mgourmet.com>

commit 3cd1ce0420ce89937bef9096d5bdb13fbdf0f8b0 upstream.

Fix problem where playback of Denon DA-300USB DAC sometimes does not
start and leads to error messages like "clock source 41 is not valid,
cannot use".

Solution: Treat this device the same as other Denon/Marantz devices in
sound/usb/quirks.c.

Tested with both PCM and DSD formats.
