If anyone has any objections, please let me know. ------------------ From: Bart Van Assche commit 61b717d041b1976530f68f8b539b2e3a7dd8e39c upstream. 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.
