The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config AB3100_CORE
drivers/mfd/Kconfig:    bool "ST-Ericsson AB3100 Mixed Signal Circuit core functions"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.  In doing
so, the debugfs unregister fcn becomes unused so we remove it too.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

The kernel WARNs and then crashes today if wm8994_device_init() fails
after calling devm_regulator_bulk_get().

That happens because there are multiple devices involved here and the
order in which managed resources are freed isn't correct.

The regulators are added as children of wm8994->dev.  Whereas,
devm_regulator_bulk_get() receives wm8994->dev as the device, though it
gets the same regulators which were added as children of wm8994->dev
earlier.

During failures, the children are removed first and the core eventually
calls regulator_unregister() for them. As regulator_put() was never done
for them (opposite of devm_regulator_bulk_get()), the kernel WARNs at

	WARN_ON(rdev->open_count);

And eventually it crashes from debugfs_remove_recursive().

Fix the kernel warnings and crashes by using regulator_bulk_get()
instead of devm_regulator_bulk_get() and explicitly freeing the supplies
in exit paths.

Tested on Exynos 5250, dual core ARM A15 machine.

Merge branches 'ib-mfd-arm-leds-4.10' and 'ib-mfd-gpio-input-regulator-4.10' into ibs-for-mfd-merged

The Kconfig and file naming for the PM8xxx driver is totally
confusing:

- Kconfig options MFD_PM8XXX and MFD_PM8921_CORE, some in-kernel
  users depending on or selecting either at random.
- A driver file named pm8921-core.c even if it is indeed
  used by the whole PM8xxx family of chips.
- An irqchip named pm8xxx since it was (I guess) realized that
  the driver was generic for all pm8xxx PMICs.

As I may want to add support for PM8901 this is starting to get
really messy. Fix this situation by:

- Remove the MFD_PM8921_CORE symbol and rely solely on MFD_PM8XXX
  and convert all users, including LEDs Kconfig and ARM defconfigs
  for qcom and multi_v7 to use that single symbol.
- Renaming the driver to qcom-pm8xxx.c to fit along the two
  other qcom* prefixed drivers.
- Rename functions withing the driver from 8921 to 8xxx to
  indicate it is generic.
- Just drop the =m config from the pxa_defconfig, I have no clue
  why it is even there, it is not a Qualcomm platform. (Possibly
  older Kconfig noise from saveconfig.)

     faster) fetching uid/gid from acl (when "cifsacl" mount option is
     enabled). NB: we are almost complete work on "cifsacl" (querying
