printing the names of non-information message about the wrong amount.

/*
* Perform a little sanity check on the regulator tree - if we found
* a number of regulators from mc13xxx_get_num_regulators_dt and
* then parsed a smaller number in mc13xxx_parse_regulators_dt then
* there is a regulator defined in the regulators node which has
* not matched any usable regulator in the driver. In this case,
* there is one missing and what will happen is the first regulator
* will get registered again.
*
* Fix this by basically making our number of registerable regulators
* equal to the number of regulators we parsed. We are allocating
* too much memory for priv, but this is unavoidable at this point.
*
* As an example of how this can happen, try making a typo in your
* regulators node (vviohi {} instead of viohi {}) so that the name
* does not match..
*
* The check will basically pass for platform data (non-DT) because
* mc13xxx_parse_regulators_dt for !CONFIG_OF will not touch num_parsed.
