Subject: sndiod: Call ctlslot->ops->sync() after every control update
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=7680e5d311d479b61f7bec6ee1378e03e513dbbd;p=openbsd

sndiod: Call ctlslot->ops->sync() after every control update

This ensures that the final NULL sioctl_ondesc() call-back
call is not lost.
