Subject: common: split.conf - don't use If.0 blocks
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=a879e50dbbcc793311c49452d4f1f304ee79a053;p=alsa-ucm-conf.git

common: split.conf - don't use If.0 blocks

Compounds starting with zero (and with continuous indexes)
are handled as array type. It means that they are appended
when they are parsed multiple times. Fix this.

Closes: https://github.com/alsa-project/alsa-ucm-conf/issues/646
