Subject: s390/qeth: indicate error when netdev allocation fails
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=778b1ac737494cec156f17c80da44664c1f77cf6;p=openwrt%2Fstaging%2Fblogic.git

s390/qeth: indicate error when netdev allocation fails

Bailing out on allocation error is nice, but we also need to tell the
ccwgroup core that creating the qeth groupdev failed.

Fixes: d3d1b205e89f ("s390/qeth: allocate netdevice early")
