Subject: af_iucv: Free iucv path/socket in path_pending callback
X-Git-Tag: MMI-PSA29.97-13-9~30395^2~8
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=65dbd7c2778f1921ef1ee2a73e47a2a126fed30f;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

af_iucv: Free iucv path/socket in path_pending callback

Free iucv path after iucv_path_sever() calls in iucv_callback_connreq()
(path_pending() iucv callback).
If iucv_path_accept() fails, free path and free/kill newly created socket.
