ALSA: hda - Fix broken reconfig
commit addacd801e1638f41d659cb53b9b73fc14322cb1 upstream.
The HD-audio reconfig function got broken in the recent kernels,
typically resulting in a failure like:
snd_hda_intel 0000:00:1b.0: control 3:0:0:Playback Channel Map:0 is already present
This is because of the code restructuring to move the PCM and control
instantiation into the codec drive probe, by the commit [bcd96557bd0a:
ALSA: hda - Build PCMs and controls at codec driver probe]. Although
the commit above removed the calls of snd_hda_codec_build_pcms() and
*_build_controls() at the controller driver probe, the similar calls
in the reconfig were still left forgotten. This caused the
conflicting and duplicated PCMs and controls.
The fix is trivial: just remove these superfluous calls from
reconfig_codec().
Fixes: bcd96557bd0a ('ALSA: hda - Build PCMs and controls at codec driver probe')
