of_find_node_by_name() walks the allnodes list, and can thus walk

 "Most of this is cleaning up various driver sysfs permissions so we can
  re-add the perm check (we unified the module param and sysfs checks,
  but the module ones were stronger so we weakened them temporarily).

  Param parsing gets documented, and also "--" now forces args to be
  handed to init (and ignored by the kernel).

  Module NX/RO protections get tightened: we now set them before calling
  parse_args()"

get_voltage_sel reads from SMPS register - if the read selector value
is 0, the SMPS is actually disabled - So, this is in addition to the
ctrl_register that may also be used to enable/disable the SMPS.

The original logic(prior to commit dbabd624d4eec50b6) used to be:
static int palmas_map_voltage_smps(struct regulator_dev *rdev,
               int min_uV, int max_uV)
<snip>
       if (min_uV == 0)
               return 0;

To handle this scenario, with the transition to regulator_list
implementation, we seem to have missed the data necessary to mark as
one of the valid entries as "0" 'disabled regulator' which results in
0 volts - So, stick with pre-existing logic.

Without this added to the list, palmas regulator driver,
on probe, attempts to setup constraints and in the case of
OMAP5uEVM, SMPS9 (which is mapped for 2v1 audio supply) fails in
regulator_list_voltage_linear_range mapping of '0', and as a fall back
of constraints not being applied, the entire regulator list is not
enumerated due to assumption that something system wide has gone bad
on with the PMIC.

Pull regulator updates from Mark Brown:
 "The bulk of the changes for this release are a few new drivers however
  there are a couple of noticable core changes and the usual stream of
  cleanups and fixes:

   - move disable of unused regulators later in init so it comes after
     deferred probe has iterated making startup smoother.
   - fixes to reference counting of the DT nodes for constraints from
     Charles Keepax.  This has little practical impact since all real
     users of the regulator bindings use FDT which doesn't need the
     reference counting.
   - lots of cleanups, especially to the Samsung drivers.
   - support for Linear Technologies LTC3589, Texas Instruments
     TPS658640 and X-Powers AXP20x"

As of commit 064d5cd110f9 (regulator: core: Fix the init of DT defined
fixed regulators) the regulator core tries to query the current voltage
of a regulator when applying constraints. This exposes a bug in the
AS3722 regulator driver which fails to read the voltage of disabled
regulators. The reason is that the hardware is programmed to a selector
of 0, but none of the voltage tables include 0 as a valid selector. The
datasheets indicate that 0 is a valid selector when the regulators are
powered off.

To fix this, add a range including selector 0 to the voltage tables.
