bf7f882b1e regulator: mc13xxx: Fix NULL pointer error in non-DT mode 
Add a check to avoid NULL pointer dereference error when
booted in non-DT mode. While at it also remove the additional
of_node_get which is no longer needed for of_get_child_by_name
and fix the node pointer.

66fda75f47 regulator: core: Replace direct ops->disable usage 
There are many places where ops->disable is called directly. Instead we
should use _regulator_do_disable() which also handles gpio regulators.

To be able to use the wrapper function from _regulator_force_disable(),
I moved the _notifier_call_chain() call from _regulator_do_disable() to
_regulator_disable(). This way, _regulator_force_disable() can use
different flags for _notifier_call_chain() without calling it twice.

30c2197103 regulator: core: Replace direct ops->enable usage 
There are some direct ops->enable in the regulator core driver. This is
a potential issue as the function _regulator_do_enable() handles gpio
regulators and the normal ops->enable calls. These gpio regulators are
simply ignored when ops->enable is called directly.

One possible bug is that boot-on and always-on gpio regulators are not
enabled on registration.

This patch replaces all ops->enable calls by _regulator_do_enable.

08221fc4e7 regulator: max14577: Fix invalid return value on DT parse success 
This fixes bug introduced in 667a6b7a (regulator: max14577: Add missing
of_node_put). The DTS parsing function returned number of matched
regulators as success status which then was compared against 0 in probe.

Result was a probe fail after successful parsing the DTS:
max14577-regulator: probe of max14577-regulator failed with error 2
