[alsa-devel] [PATCH 15/16] ALSA: hda/via - Simplify control management

Fri Jun 22 11:53:51 CEST 2018
This patch replaces the control element creations in VIA codec driver
with the standard snd_hda_gen_add_kctl() calls as a cleanup. There
are two major fields targeted by this patch: the beep controls and
static init controls.
The former is converted just like other codec drivers do. The
spec->beep_amp field can be eliminated by this change as well.
The latter, static init controls, are replaced simply with explicit
snd_hda_gen_add_kctl() calls.
After these conversions, via_build_controls() becomes superfluous and
replaced with snd_hda_gen_build_controls(), too.
