Subject: ctl: card: use an utility macro to declare GObject-derived object
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=0962a87cabc9a6d2e5774957519c8b79f272e657;p=alsa-gobject.git

ctl: card: use an utility macro to declare GObject-derived object

Since gobject v2.44, an utility macro is available to declare
GObject-derived objects.

This commit replaces existent boireplates with it.
