From 26e551c5aec572442c4ad7109ff4350f427cd39d Mon Sep 17 00:00:00 2001 From: Kamal Heib Date: Tue, 31 Jul 2018 09:02:36 +0300 Subject: [PATCH] RDMA: Fix return code check in rdma_set_cq_moderation The proper return code is "-EOPNOTSUPP" when the modify_cq() callback is not supported, all drivers should generate this and all users should check for it when detecting not supported functionality.
