staging: vchiq_arm: Avoid premature message stalls

The constants MAX_COMPLETIONS and MSG_QUEUE_SIZE control
the number of messages that can be outstanding to each client
before the system as a whole stalls. If the numbers are too
small then unnecessary thread switching will occur while
waiting for a (potentially low priority) client thread to
consume some data; badly written clients can even lead to
deadlock.

For services that carry many short messages, 16 messages can
represent a very small amount of data. Since the resources
are small - 16 bytes for a completion, 4 bytes for a message
pointer - increase the limits so they are unlikely to be hit
except in exceptional circumstances.

Merge tag 'iio-for-4.11a' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of new device support, features and cleanups for IIO in the 4.11 cycle.

It's shaping to be another fairly busy cycle. Lots more on the way!

New device support
* ads7950
  - new driver supporting ads7950, ads7951, ads7952, ads7953, ads7954,
  ads7955, ads7956, ads7957, ads7958, ads7959, ads7960, and ads7961 ADCs.
* cm3605
  - New driver for this light sensor and proximity sensor  which is an
  analog part with some additional digital controls.
* hx711
  - New driver.

Core new stuff
* Gravity sensor type.  This is a processed datastream in which the device
will try to work out which way is down.
* Split the buffer.h file into two parts. One provides the interface to 'use'
a buffer, the second provides the internals of the buffer functionality as
needed by implementations of buffers.
  - Move documentation inline so as to allow use of private: tag when
  generating documentation.
  - Add some utility functions for the few things that are directly done
  with the buffers.
  - Stop exporting functions that no-one uses outside of the core code.
  - Push docs down by the code in the c file where they should have always
  been.
  - Fix typo in kernel-doc for buffer.
  - push down some includes that were previously happening implicitly.
  - stop enabling the timestamp of the dummy device.

Features and cleanups
* ad5592r
  - ACPI support
* ad5593r
  -ACPI support.
* ad5933
  - Fix a false comment about size of a particular register.
* ad7150
  - replace S_IRUGO | S_IWUSR with 0644.  I'm not that keen on these patches
  in general, but as it was nicely presented I took this one anyway. As a
  general rule will only take these as part of a larger driver cleanup.
  - don't eat an error but rather reutnr it in the write_event_config callback.
* ad7606
  - replace non standard range attibute with _scale
* ade7753
  - use usleep_range for short sleeps
* ade7754
  - use usleep_range for short sleeps
* ade7758
  - use usleep_range for short sleeps
* ade7759
  - use usleep_range for short sleeps
* ade7854
  - use usleep_range for short sleeps
* adis16201
  - fix description
* adis16203
  - fix description
  - fix copyright year
* adis16209
  - fix description
* adt7316
  - Add braces to arms of if else statement (for consistency)
  - Alignment fixes.
* axp288
  - Fix up an issue with accidental overwrites of data.
* bmi160
  - add deivce tables for i2c and spi to support correctly identifying the
  full dt name (including manufacturer).
  - device tree binding.
* bmp280
  - use usleep_range for short sleeps.
* cm3232
  - return error from cm3232_reg_init rather than eating it if the last write
  fails.
* dummy driver
  - remove a semicolor found at end of a function defintition.
* exynos-adc
  - use usleep_range for short sleeps.
* hid-sensor (accel)
  - Add timestamp support.  The hardware can provide timestamps so lets support
  them. If not fall back to timestamps estimated in kernel.
* hid-sensor (light)
  - Add a duplicate ID for the light channels so as to keep existing interface
  whilst also using the more standard IIO interface.
* hts221
  - acpi probing
* imx25-gcq
  - Add a macro call to allow this driver to be automatically loaded.
* isl29028
  - reorganise code to avoid deep nesting of if statements.
  - move chip test and default regs into a function suitable or sharing with
  power management code.
  - tidy up some code alignment.
* lidar-lite-v3
  - introduce compatible strings that make it clear Garmin have consideral
  friends.
* mma8452
  - avoid returning signed value when unsigned is appropriate
* spmi-vadc
  - Update function for generic voltage conversion to take into account that
  different channels on this device should be handled differently.
  - Rework code to allow per channel voltage scaling and support the standard
  options for this hardware.
  - Fixup three minor issues with the above patches for this part. These all
  effect test builds rather than the native builds for the part, but good to
  clean them up anyway.
* st_sensors
  - support device matching from the ACPI DST tables.
  - acpi based probing for accelerometers
  - acpi based probing for pressure sensors
  - Allow pressure sensors to read negative values.
  - Export sampling frequency for lps25h and lps331ap.
  - Add support for the old DT bindings from the period when these deivces
  were often supported through windows.

staging: rtl: fix possible NULL pointer dereference

gcc-7 detects that wlanhdr_to_ethhdr() in two drivers calls memcpy() with
a destination argument that an earlier function call may have set to NULL:

staging/rtl8188eu/core/rtw_recv.c: In function 'wlanhdr_to_ethhdr':
staging/rtl8188eu/core/rtw_recv.c:1318:2: warning: argument 1 null where non-null expected [-Wnonnull]
staging/rtl8712/rtl871x_recv.c: In function 'r8712_wlanhdr_to_ethhdr':
staging/rtl8712/rtl871x_recv.c:649:2: warning: argument 1 null where non-null expected [-Wnonnull]

I'm fixing this by adding a NULL pointer check and returning failure
from the function, which is hopefully already handled properly.

This seems to date back to when the drivers were originally added,
so backporting the fix to stable seems appropriate. There are other
related realtek drivers in the kernel, but none of them contain a
function with a similar name or produce this warning.

iio: adc: axp288: Drop bogus AXP288_ADC_TS_PIN_CTRL register modifications

For some reason the axp288_adc driver was modifying the
AXP288_ADC_TS_PIN_CTRL register, changing bits 0-1 depending on
whether the GP_ADC channel or another channel was written.

These bits control when a bias current is send to the TS_PIN, the
GP_ADC has its own pin and a separate bit in another register to
control the bias current.

Not only does changing when to enable the TS_PIN bias current
(always or only when sampling) when reading the GP_ADC make no sense
at all, the code is modifying these bits is writing the entire register,
assuming that all the other bits have their default value.

So if the firmware has configured a different bias-current for either
pin, then that change gets clobbered by the write, likewise if the
firmware has set bit 2 to indicate that the battery has no thermal sensor,
this will get clobbered by the write.

This commit fixes all this, by simply removing all writes to the
AXP288_ADC_TS_PIN_CTRL register, they are not needed to read the
GP_ADC pin, and can actually be harmful.
