From d14939be8bfc4b7493007c365cce5d707d4fbfa1 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 21 Oct 2019 16:51:25 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: silently skip PVT ops Since mv88e6xxx_pvt_map is a static helper, no need to return -EOPNOTSUPP if the chip has no PVT, simply silently skip the operation.
