From f3763a0c1b07273218cbf5886bdf8df9df501111 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Tue, 29 Nov 2022 16:12:10 +0200 Subject: [PATCH 03/14] net: dpaa2-eth: don't use -ENOTSUPP error code dpaa2_eth_setup_dpni() is called from the probe path and dpaa2_eth_set_link_ksettings() is propagated to user space. include/linux/errno.h says that ENOTSUPP is "Defined for the NFSv3 protocol". Conventional wisdom has it to not use it in networking drivers. Replace it with -EOPNOTSUPP.
