The regulators are supposed to be controlled through the set_bias_level() component callback. Moreover, the regulators are not enabled during probe and so, this would lead to a regulator unbalanced use count.

Note this was only checked by code inspection but unless I'm missing something, it looks clear this could happen by just insmod + rmmod the module.
