From ad1f37970875eef98eeaf478f55045f388b794a5 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 6 Jul 2021 12:18:02 +0100 Subject: [PATCH] octeontx2-pf: Fix assigned error return value that is never used Currently when the call to otx2_mbox_alloc_msg_cgx_mac_addr_update fails the error return variable rc is being assigned -ENOMEM and does not return early. rc is then re-assigned and the error case is not handled correctly. Fix this by returning -ENOMEM rather than assigning rc.
