Subject: ASoC: topology: Create kcontrols based on their type
X-Git-Tag: v6.15-rc1~173^2~4^2~87^2~9
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=758beab0252912395efb79f34095c5ae7e3e58b1;p=thirdparty%2Fkernel%2Flinux.git

ASoC: topology: Create kcontrols based on their type

Fields ->ops.info and ->type of struct snd_soc_tplg_ctl_hdr denote
info-operation type and control type respectively. These are two
different pieces of information. The info type is represented by
SND_SOC_TPLG_CTL_xxx and SND_SOC_TPLG_DAPM_CTL_xxx on UAPI side whereas
for control type it is SND_SOC_TPLG_TYPE_xxx (mixer, bytes or enum).

The type of the kcontrol to be created is currently guessed based on the
value of the ->ops.info. Use the ->type instead to correct and simplify
the code. With this change ops.info() can be customized by sound drivers
utilizing the ASoC-topology just like ops.get() and ops.put() can be.
