Subject: ctl: elem-value: retrieve fixed-sized array by getter method for integer values
X-Git-Tag: v0.3.0~6
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=2e8ba2691d4dcf735d1a30ff09c0552a2dd84403;p=alsa-gobject.git

ctl: elem-value: retrieve fixed-sized array by getter method for integer values

In UAPI of Linux sound subsystem, 'struct snd_ctl_elem_values' has
fixed-sized array. It's natural to retrieve the array as is.
