em28xx: Don't do AC97 vendor detection for i2s audio devices
The current code was trying to query the AC97 registers for the vendor
information even if it was clearly not a AC97 audio device (resulting in errors
in the dmesg output). This was due to a bug in the way we did the check.
Priority: normal
Signed-off-by: Devin Heitmueller <dheitmuel...@linuxtv.org>
