From 537624db39a92e6f388fe054b9d54951e40c0746 Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Fri, 26 May 2023 22:16:27 +0200 Subject: [PATCH] generic: backport missing helper for phy interfaces The function was defined before in the patch "hack-5.15/795-backport-phylink_pcs-helpers.patch". However, the hack did not move to 6.1. Instead of using the hack do the backport of upstream accepted version.
