This shouldn't be a part of the patch.

The original driver ( drivers/iio/adc/mxs-lradc.c ) is GPLv2 , but
unless the license gets changed to BSD or somesuch, I don't think anyone
will really complain if it's changed to a more fitting version(s) of
GPL. I'm fine with any GPL version here.

Thanks for the thorough review, some points were new to me.
