Subject: brcm47xx: run ssb_pcicore_fix_sprom_core_index just for ssb bus on pci
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4815eaa4c33ef818dcd1fd5001b758f21b291674;p=openwrt%2Fstaging%2Fthess.git

brcm47xx: run ssb_pcicore_fix_sprom_core_index just for ssb bus on pci

ssb_pcicore_fix_sprom_core_index accesses the sprom on the pci bus but
this causes a data bus error (oops) on a SoC.
