The kerneldoc for regulator_is_supported_voltage() states that the
return value is a boolean. That is not correct, as it could return an
error number if the check failed.

Fix the description by expanding it to cover the valid return values and
error conditions. The description is also converted to a proper "Return"
section.

...

Not sure why you have TABs in the following lines, but I think you have checked
the rendered files (html, man, pdf) and all look good.

Alternatively it might be written as

 * Return:
 * 1 if the voltage range is supported, 0 if not, or a negative error number
 * if @regulator's voltage can't be changed and voltage readback failed.

which should be the same in the render.

(Also similar applies to the other patch(es))
