Subject: RDMA/rxe: Set wqe->status correctly if an unexpected response is received
X-Git-Tag: v5.15~8129^2~31
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=61b717d041b1976530f68f8b539b2e3a7dd8e39c;p=platform%2Fkernel%2Flinux-starfive.git

RDMA/rxe: Set wqe->status correctly if an unexpected response is received

Every function that returns COMPST_ERROR must set wqe->status to another
value than IB_WC_SUCCESS before returning COMPST_ERROR. Fix the only code
path for which this is not yet the case.
