From a52c8e2469c30cf7ac453d624aed9c168b23d1af Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Tue, 28 May 2019 14:37:28 +0300 Subject: RDMA: Clean destroy CQ in drivers do not return errors Like all other destroy commands, .destroy_cq() call is not supposed to fail. In all flows, the attempt to return earlier caused to memory leaks. This patch converts .destroy_cq() to do not return any errors.
