regulator_get_exclusive — obtain exclusive access to a regulator.
|struct device * dev,|
|const char * id|

IS_ERR condition containing errno. Other consumers will be
unable to obtain this regulator while this reference is held and the
use count for the regulator will be initialised to reflect the current
state of the regulator.
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.
Use of supply names configured via
