From: Nicolai Stange
Date: Mon Mar 07 2016 - 14:30:25 EST


As discovered by the kbuild test robot, an allmodconfig build on
microblaze bails out with

ERROR: "isa_io_base" [sound/pci/vx222/snd-vx222.ko] undefined!
ERROR: "isa_io_base" [sound/pci/trident/snd-trident.ko] undefined!
ERROR: "isa_io_base" [sound/pci/snd-via82xx.ko] undefined!
ERROR: "isa_io_base" [sound/pci/snd-via82xx-modem.ko] undefined!
ERROR: "isa_io_base" [sound/pci/snd-sonicvibes.ko] undefined!
[... plus dozens more throughout the tree]

Export isa_io_base to modules by means of EXPORT_SYMBOL().
