+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.
