From a7ca4c3ebe6994ba88eb23576b2c3901b08e1dec Mon Sep 17 00:00:00 2001 From: Jing Xiangfeng Date: Wed, 17 Jun 2020 22:08:03 +0800 Subject: [PATCH] IB/srpt: Remove WARN_ON from srpt_cm_req_recv The callers pass the pointer '&req' or 'private_data' to srpt_cm_req_recv(), and 'private_data' is initialized in srp_send_req(). 'sdev' is allocated and stored in srpt_add_one(). It's easy to show that sdev and req are always valid. So we remove unnecessary WARN_ON.
