X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f631d1576ddb331ceee726d876ea9c74a3553dbc;p=thirdparty%2Fopenwrt.git

unetmsg: add null check in TX disconnect callback

The network may be deleted before the disconnect callback fires.
Check for null to avoid crash when accessing net.tx_channels.
