From bc87a0036826a37b43489b029af8143bd07c6cca Mon Sep 17 00:00:00 2001 From: Gavi Teitz Date: Mon, 11 Mar 2019 11:56:34 +0200 Subject: [PATCH] net/mlx5e: Fix error handling when refreshing TIRs Previously, a false positive would be caught if the TIRs list is empty, since the err value was initialized to -ENOMEM, and was only updated if a TIR is refreshed. This is resolved by initializing the err value to zero.
