Subject: RDMA/cxgb4: Use dst parameter in import_ep()
X-Git-Tag: v3.5-rc1~171^2^2~13
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bd61baaf59669accae2720799394a51fecabe5d9;p=profile%2Fivi%2Fkernel-x86-ivi.git

RDMA/cxgb4: Use dst parameter in import_ep()

Function import_ep() is incorrectly using ep->dst instead of the dst
ptr passed in.  This causes a crash when accepting new rdma connections
becase ep->dst is not initialized yet.
