[ALSA] hda-codec - Don't return error at initialization of modem codec

Some modem codec seem to fail in the initialization, and this
stopped loading of the whole module although the audio is OK.
Since it's usually a non-fatal issue, the driver tries to proceed
to initialize now.

This should be fixed in the latest kernel, 2911.6.3, available at:

Please test.

Comment 4 Russ Price 2007-03-13 23:08:58 UTC
Sound worked OK on 2911.6.4, but disappeared on 2911.6.5.

The only clue to any problem in dmesg:

   hda-intel: no codecs initialized

System: Intel D101GGC motherboard, Celeron D 336 CPU
Running the x86_64 version of FC6.

Workaround: continue running 2911.6.4.

Comment 5 Chuck Ebbert 2007-03-26 20:20:50 UTC
Fixed in 2.6.20-1.2933.fc6
