Pull power management and ACPI updates from Rafael Wysocki:
"Included are: a somewhat late devfreq update which however is mostly
fixes and cleanups with one new thing only (the PPMUv2 support on
Exynos5433), an ACPI cpufreq driver fixup and two ACPI core cleanups
related to preprocessor directives.Specifics:
- Fix a memory allocation size in the devfreq core (Xiaolong Ye).
- Fix a mistake in the exynos-ppmu DT binding (Javier Martinez
Canillas).- Add support for PPMUv2 ((Platform Performance Monitoring Unit
version 2.0) on the Exynos5433 SoCs (Chanwoo Choi).- Fix a type casting bug in the Exynos PPMU code (MyungJoo Ham).
- Assorted devfreq code cleanups and optimizations (Javi Merino,
MyungJoo Ham, Viresh Kumar).- Fix up the ACPI cpufreq driver to use a more lightweight way to get
to its private data in the ->get() callback (Rafael J Wysocki).- Fix a CONFIG_ prefix bug in one of the ACPI drivers and make the
ACPI subsystem use IS_ENABLED() instead of #ifdefs in function

Some of the device files are required to be user accessible for PSM while
most should remain accessible only by root.Add a parameter to hfi1_cdev_init which controls if the user should have access
to this device which places it in a different class with the appropriate
devnode callback.In addition set the devnode call back for the existing class to be a bit more
explicit for those permissions.Finally remove the unnecessary null check before class_destroy

Pull irq updates from Thomas Gleixner:
"This is a rather large update post rc1 due to the final steps of
cleanups and API changes which had to wait for the preparatory patches
to hit your tree.- Regression fixes for ARM GIC irqchips
- Regression fixes and lockdep anotations for renesas irq chips
- The leftovers of the cleanup and preparatory patches which have
been ignored by maintainers- Final conversions of the newly merged users of obsolete APIs
- Final removal of obsolete APIs
- Final removal of ARM artifacts which had been introduced during the
conversion of ARM to the generic interrupt code.- Final split of the irq_data into chip specific and common data to
reflect the needs of hierarchical irq domains.- Treewide removal of the first argument of interrupt flow handlers,
i.e. the irq number, which is not used by the majority of handlers
and simple to retrieve from the other argument the irq descriptor.- A few comment updates and build warning fixes"

The commit [b67893206fc0: leds:lp55xx: fix firmware loading error]
tries to address the firmware file handling with user helper, but it
sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK. Since the
wrong option was enabled, the system got a regression -- it suffers
from the unexpected long delays for non-present firmware files.This patch corrects the Kconfig dependency to the right one,
CONFIG_FW_LOADER_USER_HELPER. This doesn't change the fallback
behavior but only enables UMH when needed.Bugzilla: https://bugzilla.opensuse.org/show_bug.cgi?id=944661

If a mux clock is initialised (by hardware or firmware) with an
invalid parent, its ->get_parent() can return an out of range
index. For example, the generic mux clock attempts to return
-EINVAL, which due to the u8 return type ends up a rather large
number. Using this index with the parent_names[] array results
in an invalid pointer and (usually) a crash in the following
strcmp().This patch adds a check for the parent index being in range,
ignoring clocks reporting invalid values.Signed-off-by: Mans Rullgard
