Subject: USB-Audio: ALC4080 - fix 'detect S/PDIF device using find-pcm'
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=706d1634b3f23ba2ffee506d2fab9cd3b8767153;p=alsa-ucm-conf.git

USB-Audio: ALC4080 - fix 'detect S/PDIF device using find-pcm'

The find-device may be NULL, so use double $$ to reference
the variable (skip NULL check).
