Returns a struct regulator corresponding to the regulator producer,
or <code class="function">IS_ERR</code> condition containing errno. Other consumers will be
unable to obtain this reference is held and the use count for the
regulator will be initialised to reflect the current state of the
regulator.
</p><p>
This is intended for use by consumers which cannot tolerate shared
use of the regulator such as those which need to force the
regulator off for correct operation of the hardware they are
controlling.
</p><p>
Use of supply names configured via <code class="function">regulator_set_device_supply</code> is
strongly encouraged. It is recommended that the supply name used
should match the name used for the supply and/or the relevant
device pins in the datasheet.
