Function devm_enable_optional

pub fn devm_enable_optional(dev: &Device<Bound>, name: &CStr) -> Result

Same as devm_enable, but calls devm_regulator_get_enable_optional instead.

This obtains and enables a devres-managed regulator for a device, but does not print a message nor provides a dummy if the regulator is not found.

This calls regulator_disable() and regulator_put() automatically on driver detach.
