From 260ac1c66dd77b45dde22565ed4ab5ad180a1a03 Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Tue, 26 Feb 2019 17:17:00 +0530 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.
