Add support for setting up GPIO pin interrupts in the lpc18xx pinctrl
driver. The LPC18xx SCU contain two registers that sets up the signal
routing to the GPIO pin interrupt (PINT) block. The routing uses the
GPIO namespace and not the pin namespace so a lookup is preformed on
the pin.
Routing configuration is done in the device tree by using the new
nxp,gpio-pin-interrupt property. This property takes single parameter
which sets the PINT hwirq for the GPIO.

pinctrl_find_gpio_range_from_pin takes the pctldev->mutex but so
does pinconf_pins_show and this will cause a deadlock if
pinctrl_find_gpio_range_from_pin is used in .pin_config_get

Create a nolock version of pinctrl_find_gpio_range_from_pin to
allow pin to gpio lookup to be used from pinconf_pins_show.

The initialization of ngroups is occurring at the end of the
first iteration of the outer loop, which means that the
assignment pins[ngroups++] = i is potentially indexing into
a region outside of array pins because ngroups is not initialized.
Instead, initialize ngroups in the inner loop before the first

Tiny fixes branch this week, in fact only one patch.
Turns out the USB support for a Renesas board was developed on a pre-release
board that ended up being changed before shipping. To avoid breakage on those
boards, and avoid confusion, it's a reasonable idea to patch now instead of
later. There are no known users of the pre-release variant any more.

XFS uses CRC verification over a sub-range of the head of the log to
detect and handle torn writes. This torn log write detection currently
runs unconditionally at mount time, regardless of whether the log is
dirty or clean. This is problematic in cases where a filesystem might
end up being moved across different, incompatible (i.e., opposite
byte-endianness) architectures.
The problem lies in the fact that log data is not necessarily written in
an architecture independent format. For example, certain bits of data
are written in native endian format. Further, the size of certain log
data structures differs (i.e., struct xlog_rec_header) depending on the
word size of the cpu. This leads to false positive crc verification
errors and ultimately failed mounts when a cleanly unmounted filesystem
is mounted on a system with an incompatible architecture from data that
was written near the head of the log.
Update the log head/tail discovery code to run torn write detection only
when the log is not clean. This means something other than an unmount
record resides at the head of the log and log recovery is imminent. It
is a requirement to run log recovery on the same type of host that had
written the content of the dirty log and therefore CRC failures are
legitimate corruptions in that scenario.

Once the record at the head of the log is identified and verified, the
in-core log state is updated based on the record. This includes
information such as the current head block and cycle, the start block of
the last record written to the log, the tail lsn, etc.
Once torn write detection is conditional, this logic will need to be
reused. Factor the code to update the in-core log data structures into a
new helper function. This patch does not change behavior.

Once the mount sequence has identified the head and tail blocks of the
physical log, the record at the head of the log is located and examined
for an unmount record to determine if the log is clean. This currently
occurs after torn write verification of the head region of the log.
This must ultimately be separated from torn write verification and may
need to be called again if the log head is walked back due to a torn
write (to determine whether the new head record is an unmount record).
Separate this logic into a new helper function. This patch does not
change behavior.

The code that locates the log record at the head of the log is buried in
the log head verification function. This is fine when torn write
verification occurs unconditionally, but this behavior is problematic
for filesystems that might be moved across systems with different
architectures.
In preparation for separating examination of the log head for unmount
records from torn write detection, lift the record location logic out of
the log verification function and into the caller. This patch does not
change behavior.

This patch fixes a recent ABORT_TASK regression associated

a command has already been completed, and explicit ABORT must
be avoided.
Note commit febe562c dropped the local kref_get_unless_zero()
check in core_tmr_abort_task(), but did not drop this extra
corresponding target_put_sess_cmd() in the failure path.
So go ahead and drop this now bogus target_put_sess_cmd(),
and avoid this potential use-after-free.

[media] media: davinci_vpfe: fix missing unlock on error in vpfe_prepare_pipeline()
This is a port of the patch "drm/amdgpu: Fix error handling in amdgpu_flip_work_func."
to fix the following problem for radeon as well which was
reported against amdgpu:
The patch e1d09dc0cc: "drm/amdgpu: Don't hang in
amdgpu_flip_work_func on disabled crtc." from Feb 19, 2016, leads to
the following static checker warning, as reported by Dan Carpenter in
https://lists.freedesktop.org/archives/dri-devel/2016-February/101987.html
drivers/gpu/drm/amd/amdgpu/amdgpu_display.c:127 amdgpu_flip_work_func() warn: should this be 'repcnt == -1'
drivers/gpu/drm/amd/amdgpu/amdgpu_display.c:136 amdgpu_flip_work_func() error: double unlock 'spin_lock:&crtc->dev->event_lock'
drivers/gpu/drm/amd/amdgpu/amdgpu_display.c:136 amdgpu_flip_work_func() error: double unlock 'irqsave:flags'
This patch fixes both reported problems:
Change post-decrement of repcnt to pre-decrement, so
it can't underflow anymore, but still performs up to
three repetitions - three is the maximum one could
expect in practice.
Move the spin_unlock_irqrestore to where it actually
belongs.

ADM1278 is mostly compatible to other chips of the same series.
Besides the usual difference in coefficients, it supports
a temperature sensor, and it can measure both input and output
voltage at the same time.

Change iio_hwmon nodes to use hypen in node names instead of
underscore.

Currently the driver calls hwmon_device_register_with_groups which
does not accept hypen in node name and returns EINVAL. Use of hypen
in device tree node name results in probe failure., however use of
hypen in device tree node name is perfectly acceptable.
Change this by allocating a duplicate managed string, replacing
hypen with underscore and then calling hwmon_device_register_with_groups.
This allows the use of hypen in device tree node name while maintaining
backwards compatibility and preventing any possible regressions with
user space.

This adds support for the Linear Technology LTC2990 I2C System Monitor.
The LTC2990 supports a combination of voltage, current and temperature
monitoring. This driver currently only supports reading two currents
by measuring two differential voltages across series resistors, in
addition to the Vcc supply voltage and internal temperature.
This is sufficient to support the Topic Miami SOM which uses this chip
to monitor the currents flowing into the FPGA and the CPU parts.

The vexpress hwmon implementation is currently just called vexpress.
This is a problem because it clashes with another module with the same
name in regulators.
This patch renames the vexpress hwmon implementation to vexpress-hwmon
so that there will be no clash in the module namespace.

This reverts commit ef50c04633.
So adding -Werror=incompatible-pointer-types wasn't a bad idea, but it
should really not be done in the scheduler tree: it exposes us to a
number of pre-existing warnings (most of them harmless), now upgraded
to build failures...
This should be done via the kbuild tree.
