Applied to hwmon-next.

Please check your e-mail settings: checkpatch complains about a
mismatch between Naresh.Solanki@9elements.com and
naresh.solanki@9elements.com. Not that it matters in this case,
but it is annoying to get a checkpatch alert each time I apply
one of your patches.

Thanks,
Guenter
