Here is the patch that I'm using.  https://patchwork.ozlabs.org/patch/605758/

It is intended to apply to http://git.denx.de/?p=u-boot.git;a=summary

I've been executing spatch using this command line within the U-Boot
source tree:

spatch --in-place --sp-file scripts/coccinelle/net/mdio_register.cocci .

OK, good to know. If there is anything I can do to make it easier to
reproduce, please let me know.

Thanks,
