Pull module updates from Rusty Russell:
"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()"

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"

When a regulator is defined using DT and it has a single voltage the
regulator init always tries to apply this voltage. However it fails if
the regulator isn't settable because it is using an internal low level
function. To overcome this we now first query the regulator and only
set it if needed.

regulator_init_complete does a scan of regulators which dont have
always-on or consumers are automatically disabled as being unused.
However, with deferred probing, late_initcall() is too soon to
declare a regulator as unused as the regulator itself might not
have registered due to defferal - Example: A regulator deffered due
to i2bus not available which in turn is deffered due to pinctrl
availability.
Since deferred probing is done in late_initcall(), do the cleanup of
unused regulators by regulator_init_complete in late_initcall_sync
instead of late_initcall.

In the spirit of conservatism that governs our general approach to
permissions it is better if we don't touch regulators we weren't explicitly
given permissions to control. This avoids the need to explicitly specify
unknown regulators in DT as always on, if a regulator is not otherwise
involved in software control it can be omitted from the DT.
Regulators explicitly given constraints in DT still need to have an always
on constraint specified as before.

commit 2cce4be9e6 "regulator: arizona-ldo1: Add processing of init_data

did not add an #include to the header file declaring that function.
I got a build error when doing randconfig testing on this, which
is fixed by this patch to include of.h.

When fixed_uV is set and n_voltage is 1, regulator core will return
rdev->desc->fixed_uV in regulator_get_voltage() and regulator_list_voltage().
Rename ltc3589_standby_regulator_ops to ltc3589_fixed_standby_regulator_ops,
this makes the code clear that the ops is for fixed voltage regulator.
