Use devm_input_allocate_device to simplify the error handling code.
This conversion also makes input_register_device() to be called after
acpi_remove_notify_handler. This avoid a small window that it's possible

ModPhy Common lanes can provide the clock gating status for the important
system PLLs such as Gen2 USB3PCIE2 PLL, DMIPCIE3 PLL, SATA PLL and MIPI
PLL.
On SPT, in addition to the crystal oscillator clock, the 100Mhz Gen2
USB3PCI2 PLL clock is used as the PLL reference clock and Gen2 PLL idling
is a necessary condition for the platform to go into low power states like
PC10 and S0ix.

The PCH implements a number of High Speed I/O (HSIO) lanes that are split
between PCIe*, USB 3.0, SATA, GbE, USB OTG and SSIC. This patch shows the
current power gating status of the available ModPhy Core lanes. This is
done by sending a message to the PMC (MTPMC) that contains the XRAM
register offset for the MPHY_CORE_STS_0 and MPHY_CORE_STS_1 and then by
reading the response sent by the PMC (MFPMC).
While enabling low power modes we often encounter situations when the
ModPhy lanes are not power gated and it becomes hard to debug which lane is
active and which is not in the absence of an external hardware debugger
(JTAG/ITP). This patch eliminates the dependency on an external hardware
debugger for reading the ModPhy Lanes power gating status.
This patch requires PMC_READ_DISABLE setting to be disabled in the platform
bios.

This patch adds the support for reading the power gating status of various
devices present on Sunrise Point PCH. This is intended to be used for
debugging purpose while tuning the platform for power optimizations and
also to understand which devices (on PCH) are blocking the system to enter
a low power state.
Power Management Controller on Sunrise Point PCH provides access to "PGD
PFET Enable Ack Status Registers (ppfear)". This patch reads and decodes
this register and dumps the output in formatted manner showing various
devices present on the PCH and their "Power Gating" status.
Further documentation can be found in Intel 7th Gen Core family mobile u/y
processor io datasheet volume 2.
Sample output (stripped and not in order):
cat /sys/kernel/debug/pmc_core/pch_ip_power_gating_status

On Sunrise Point PCH, the Power Management Controller provides 4K bytes of
memory space for various power management and debug registers. This fix is
needed to access power management & debug registers that are mapped at a
higher offset.
Also, this provides a fix for correctly masking the PWRMBASE as the initial
bits (0-11) are reserved.

The AMW0_GUID1 wmi is not only found on Acer family but also other
machines like Lenovo, Fujitsu and Medion. In the past, acer-wmi handled
those non-Acer machines by quirks list.
But actually acer-wmi driver was loaded on any machine that had
AMW0_GUID1. This behavior is strange because those machines should be
supported by appropriate wmi drivers. e.g. fujitsu-laptop,
ideapad-laptop.
This patch adds the logic to check the machine that has AMW0_GUID1
should be in Acer/Packard Bell/Gateway white list. But, it still keeps
the quirk list of those supported non-acer machines for backward
compatibility.

Patches queued up by Filipe:
The most important change is still the fix for the extent tree
corruption that happens due to balance when qgroups are enabled (a
regression introduced in 4.7 by a fix for a regression from the last
qgroups rework). This has been hitting SLE and openSUSE users and QA
very badly, where transactions keep getting aborted when running
delayed references leaving the root filesystem in RO mode and nearly
unusable. There are fixes here that allow us to run xfstests again
with the integrity checker enabled, which has been impossible since 4.8
(apparently I'm the only one running xfstests with the integrity
checker enabled, which is useful to validate dirtied leafs, like
checking if there are keys out of order, etc). The rest are just some
trivial fixes, most of them tagged for stable, and two cleanups.

framework. The only patch that can even be considered "core" adds another
clk_get() variant. The rest of the changes are in drivers for various SoCs, and
we have a few bits for ARM shmobile architecture code (dts and mach) due to the
dependency we're breaking between shmobile architecture code and its clk
driver. Those shmobile bits have also been pulled into arm-soc tree. Here's the
summary:
Core:
- Support for devm_get_clk_from_child() used with DT bindings that have
subnodes with the 'clocks' property
New Drivers:
- Allwinner A64 (sun50i)
- i.MX imx6ull

Introduces remoteproc "subdevice" support, which allows remoteproc
driver to associate devices to the "running" state of the remoteproc,
allowing devices to be probed and removed as the remote processor is
booted, shut down or recovering from a crash.
Handling of virtio device resources was improved, vring memory is now
allocated as part of other memory allocation. This ensures that all
vrings for all virtio devices are allocated before we boot the remote
processor.
The debugfs mechanism for starting and stopping remoteproc instances was
replaced with a sysfs interface, also providing a mechanism for
specifying firmware to use by the instance. This allows user space to
load and boot use case specific firmware on remote processors.
New drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as
removal of the unused StE modem loader.
Finally support for crash recovery in the Qualcomm Wirelss subsystem
(used for WiFi/BT/FM on a number of platforms) and a number of bug fixes
and cleanups.

regmap: cache: Remove unused 'blksize' variable
Shift down default message verbosity, where it does not show
error results in stdout by default. Since that behavior
is the same as giving the --quiet option, this patch removes
--quiet and makes --verbose increasing verbosity.
In other words, this changes verbosity options as below.

ftracetest -> ftracetest -v
ftracetest -v -> ftracetest -v -v (or -vv)

No core changes this time. Mainly gradual improvement and
feature growth in the drivers.
New drivers:
- New driver for TI DA850/OMAP-L138/AM18XX pinconf
- The SX150x was moved over from the GPIO subsystem and
reimagined as a pin control driver with GPIO support
in a joint effort by three independent users of this
hardware. The result was amazingly good!
- New subdriver for the Oxnas OX820
Improvements:
- The sunxi driver now supports the generic pin control
bindings rather than the sunxi-specific. Add debouncing
support to the driver.
- Simplifications in pinctrl-single adding a generic parser.
- Two downstream fixes and move the Raspberry Pi BCM2835 over
to use the generic GPIOLIB_IRQCHIP.

Core changes:
- Simplify threaded interrupt handling: instead of passing
numbed parameters to gpiochip_irqchip_add_chained() we
create a new call: gpiochip_irqchip_add_nested() so the two
types are clearly semantically different. Also make sure
that all nested chips call gpiochip_set_nested_irqchip()
which is necessary for IRQ resend to work properly if
it happens.
- Return error on seek operations for the chardev.
- Clamp values set as part of gpio[d]_direction_output() so
that anything != 0 will be send down to the driver as "1"
not the value passed in.
- ACPI can now support naming of GPIO lines, hogs and holes
in the GPIO lists.
New drivers:
- The SX150x driver was deemed unfit for the GPIO subsystem
and was moved over to a combined GPIO+pinctrl driver in the
pinctrl subsystem.
New features:
- Various cleanups to various drivers.

mesh_sync_offset_adjust_tbtt() implements Extensible synchronization

Add a new "global" (i.e. not per-rfkill device) LED trigger, rfkill-any,
which may be useful on laptops with a single "radio LED" and multiple
radio transmitters. The trigger is meant to turn a LED on whenever
there is at least one radio transmitter active and turn it off
otherwise.
This requires taking rfkill_global_mutex before calling rfkill_set_block()
in rfkill_resume(): since __rfkill_any_led_trigger_event() is called from
rfkill_set_block() unconditionally, each caller of the latter needs to
take care of locking rfkill_global_mutex.

Add the ability for an AP (and associated VLANs) to perform
multicast-to-unicast conversion for ARP, IPv4 and IPv6 frames
(possibly within 802.1Q). If enabled, such frames are to be sent
to each station separately, with the DA replaced by their own
MAC address rather than the group address.
Note that this may break certain expectations of the receiver,
such as the ability to drop unicast IP packets received within
multicast L2 frames, or the ability to not send ICMP destination
unreachable messages for packets received in L2 multicast (which
is required, but the receiver can't tell the difference if this
new option is enabled.)
This also doesn't implement the 802.11 DMS (directed multicast
service).
