Declare regulator_ops structure as const as it is only stored in the ops
field of a regulator_desc structure. This field is of type const, so
regulator_ops structures having this property can be made const too.

These of_node_get() were added to balance refcount decrements inside of
of_find_node_by_name().
See: commit c92f5dd2c4 ("regulator: Add missing of_node_put()")
However of_find_node_by_name() was then replaced by of_get_child_by_name(),
which doesn't call of_node_put() against its input parameter.
So, need to remove these unnecessary of_node_get() calls.

of_find_node_by_name walks the allnodes list, and can thus walk

of_find_node_by_name() returns a node pointer with refcount incremented, use
of_node_put() on it when done.
of_find_node_by_name() will call of_node_put() against from parameter,
thus we also need to call of_node_get(from) before calling
of_find_node_by_name().

The dev parameter is the device requesting the data.
In this case it should be &pdev->dev rather than pdev->dev.parent.
The dev parameter is used to call devm_kzalloc in of_get_regulator_init_data(),
which means this fixes a memory leak because the memory is allocated every time
probe() is called, thus it should be freed when this driver is unloaded.

If a regulator is not used by a board, it's quite legitimate not to
provide platform data or a device tree node to configure it (i.e.
regulator_init_data). In that case, during MAX8907 regulator's
probe(), the idata variable will be NULL for that regulator. Prevent
dereferincing it.
If the MBATT regulator's init_data is not specified, or no name was
specified in the constraints, the regulator will be named based on
the regulator descriptor, so initialize mbatt_rail_name from there.

The MAX8907 is an I2C-based power-management IC containing voltage
regulators, a reset controller, a real-time clock, and a touch-screen
controller.
The original driver was written by:
* Gyungoh Yoo <jack.yoo@maxim-ic.com>
Various fixes and enhancements by:
* Jin Park <jinyoungp@nvidia.com>
* Tom Cherry <tcherry@nvidia.com>
* Prashant Gaikwad <pgaikwad@nvidia.com>
* Dan Willemsen <dwillemsen@nvidia.com>
* Laxman Dewangan <ldewangan@nvidia.com>
During upstreaming, I (swarren):
* Converted to regmap.
* Allowed probing from device tree.
* Reworked the regulator driver to be represented as a single device that
provides multiple regulators, rather than as a device per regulator.
* Replaced many regulator ops with standard functions.
* Added ability to specify supplies for each regulator.
* Removed the WLED regulator. If/when we expose this in the driver, it
should be a backlight object not a regulator object.
* Renamed from max8907c->max8907, since the driver covers at least the
C and B revisions.
* General cleanup.
