Note that the warning is bogus, the function can never be called with invalid
'peripheral' argument. GCC just cannot analyze this.

Fix for this issue has been already posted :-) (one week ago)
http://patchwork.ozlabs.org/patch/327065/
But I don't mind if Marek's patch will be applied directly by Tom
before v2014.04 is released :-)

Aren't you missing the exynos5_mmc_config() in your patch ? Otherwise, I don't
mind either way and I'd prefer if your patch (which came in earlier) was applied
of course (unless you are missing the _mmc_config).
