From 14ba87304bf98a0a0c069708bb14e92a616420d1 Mon Sep 17 00:00:00 2001 From: Weihang Li Date: Fri, 22 May 2020 21:02:56 +0800 Subject: RDMA/hns: Remove redundant type cast for general pointers There is no need to do a type cast on genernal pointers, they could be assigned to any type of variables. In addition, optimize initialization of some variables and adjust order of them.
