Subject: ALSA: pcm: Fix pcm_class sysfs output
From: Takashi Iwai <[email protected]>
commit 60b93030b44a8c2cd015cebe5624fd7552ec67ec upstream.
The pcm_class sysfs of each PCM substream gives only "none" since the
recent code change to embed the struct device. Fix the code to point
directly to the embedded device object properly.
Fixes: ef46c7af93f9 ('ALSA: pcm: Embed struct device')
