Subject: isdn: mISDN: set ->family in ->getname()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d9152097acc5f9fdc0bf1a8e3454634dfae47742;p=openwrt%2Fstaging%2Fblogic.git

isdn: mISDN: set ->family in ->getname()

The "maddr->family" variable was not set but instead it leaked stack
information to userspace.
