From c689c4867286888099c21e02d2494f047060d06f Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Mon, 4 Mar 2019 16:01:30 +0100 Subject: [PATCH] net: phy: Reloc next and prev pointers inside phy_drivers This patch relocates the pointers inside phy_drivers incase of manual reloc. Without this reloc, these points to invalid pre relocation address and hence causes exception or hang.
