Subject: net: phy: Reloc next and prev pointers inside phy_drivers
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=260ac1c66dd77b45dde22565ed4ab5ad180a1a03;p=thirdparty%2Fu-boot.git

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.
