Subject: [PATCH] ALSA: emu10k1: don't create old pass-through playback device
 on Audigy
References: bsc#1012628
Patch-mainline: 6.2.12
Git-commit: 8dd13214a810c695044aa168c0ddba1a9c433e4f

commit 8dd13214a810c695044aa168c0ddba1a9c433e4f upstream.

It could have never worked, as snd_emu10k1_fx8010_playback_prepare() and
snd_emu10k1_fx8010_playback_hw_free() assume the emu10k1 offset for the
ETRAM, and the default DSP code includes no handler for it. It also
wouldn't make a lot of sense to make it work, as Audigy has an own, much
simpler, pass-through mechanism. So just skip creation of the device.
