[PATCH 2/2] ASoC: dapm: mark 'snd_soc_dapm_free_kcontrol' as static

[Arnd Bergmann <arnd@arndb.de>]

The newly introduced function is declared as globally visible,
but is not declared in a header, causing a warning 'make W=1'
or 'make C=1':

sound/soc/soc-dapm.c:3782:1: warning: symbol 'snd_soc_dapm_free_kcontrol' was not declared. Should it be static?

The suggestion to make it static seems appropriate here, so let's
do that.

Fixes: 19ad683abc85 ("ASoC: dapm: Avoid creating kcontrol for params")
