From e12ee8ce51435c4d24f437f10e0fce773505c674 Mon Sep 17 00:00:00 2001 From: Zhu Yanjun Date: Mon, 23 Apr 2018 03:57:58 -0400 Subject: [PATCH] IB/rxe: remove unused function variable In the functions rxe_mem_init_dma, rxe_mem_init_user, rxe_mem_init_fast and copy_data, the function variable rxe is not used. So this function variable rxe is removed.
