The kerneldoc for regulator_is_supported_voltage() states that the

error number if the check failed.

I don't know what error number means. Is it positive? Negative?

s/error number/negative error code/g
(Here and everywhere else)

Fix the description by expanding it to cover the true, false and error

true and false are not what is returned, right?

conditions. The description is also converted to a proper "Return"
section.

...

- * Returns a boolean.
+ * Return: 1 if voltage range is support, 0 if not, or error number if

supported

+ *	   voltage can't be changed and voltage readback failed.
