[alsa-devel] [PATCH v3] amixer: skip showing asoc tlv byte controls
ASoC TLV Byte controls are very large size controls so we should add new options for these. So skip dumping contents for these.
$amixer -c0 cget numid=16 numid=16,iface=MIXER,name='mdl params' ; type=BYTES,access=-----RW-,values=30336 : ASoC TLV Byte control, skipping bytes dump

Use semicolon instead.

Sure, I tried to use the existing style, what is the interpretation of these?
