We were not calling of_node_put if the regulator failed to register this
patch fixes this.

Pull driver core update from Greg KH:
"Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.
Everything has been in linux-next for a while"
* tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (324 commits)
Revert "ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file entries"
fs: debugfs: add forward declaration for struct device type
firmware class: Deletion of an unnecessary check before the function call "vunmap"
firmware loader: fix hung task warning dump
devcoredump: provide a one-way disable function
device: Add dev_<level>_once variants
ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file entries
ath: use seq_file api for ath9k debugfs files
debugfs: add helper function to create device related seq_file
drivers/base: cacheinfo: remove noisy error boot message
Revert "core: platform: add warning if driver has no owner"
drivers: base: support cpu cache information interface to userspace via sysfs
drivers: base: add cpu_device_create to support per-cpu devices
topology: replace custom attribute macros with standard DEVICE_ATTR*
cpumask: factor out show_cpumap into separate helper function
driver core: Fix unbalanced device reference in drivers_probe
driver core: fix race with userland in device_add()
sysfs/kernfs: make read requests on pre-alloc files use the buffer.
sysfs/kernfs: allow attributes to request write buffer be pre-allocated.
fs: sysfs: return EGBIG on write if offset is larger than file size

The of_get_regulator_init_data() function is used to extract the regulator
init_data but information on how to extract certain data is defined in the
static regulator descriptor (e.g: how to map the hardware operating modes).
Add a const struct regulator_desc * parameter to the function signature so
the parsing logic could use the information in the struct regulator_desc.
of_get_regulator_init_data() relies on of_get_regulation_constraints() to
actually extract the init_data so it has to pass the struct regulator_desc
but that is modified on a later patch.

This patch sets ena_gpio_initialized for all drivers which set a
ena_gpio from parsed DT properties. Drivers using pdata may get zero
initialized pdata and therefore copy a 0 into the regulator_config
ena_gpio field.

commit 2cce4be9e6b8 "regulator: arizona-ldo1: Add processing of init_data
from device tree" added a call to of_get_child_by_name() but
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.

It is more idiomatic to process things relating to the regulator in its
driver. This patch moves both processing of device tree relating to the
regulator and checking if the regulator is external from arizona-core
into the regulator driver.

Both 5102 and 8997 have the regulator capable of supplying 1.8V, and the
voltage step from the 5110 regulator is different from what is specified
in the default description. This patch updates the default regulator
description to match 5110 and selects the 1.8V capable description for
8997.
