X-Git-Tag: v1.1.2~134
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=5d23c406d1757d1b65e1d17a71c69620d9af71d7;p=alsa-lib.git

topology: Fix pcm ID & name parsing

The name and ID of SectionPCM should be set to pcm_name and pcm_id,
for a front-end DAI link in the kernel, not for the front-end DAI
of the link.
