Second set of IIO new device support, features and cleanup for the 4.14 cycle.

New device support:
* ak8974
  - support the AMI306.
* st_magnetometer
  - add support for the LIS2MDL with bindings.
* rockchip-saradc
  - add binding for rv1108 SoC (no driver change).
* srf08
  - add srf02 (i2c only) and srf10 support.
* stm32-timer
  - support for the STM32H7 to existing driver.

Features:
* tools
  - move over to the tools buildsystem rather than hand rolling.
  - add an install section to the build.
* ak8974
  - use serial number to add device randomness.
  - add AMI306 calibration data output.
* ccs811
  - triggered buffer support.
* srf08
  - add a device tree table as the old style i2c probing is going away,
  - add triggered buffer support
* st32-adc
  - add optional st,min-sample-time-nsecs binding to allow control of
    sampling against analog circuitry.
* stm32-timer
  - add output compare triggers.
* ti-ads1015
  - add threshold event support.
* ti-ads7950
  - Allow use on ACPI platforms including providing a default reference
    voltage as there is no way to obtain this on ACPI currently.

Cleanup and fixes:
* ad7606
  - fix an error return code in probe.
* ads1015
  - fix incorrect data rate setting update when capture in progress,
  - fix wrong scale information for the ADS1115,
  - make conversions work when CONFIG_PM is not set,
  - make sure we don't get a stale result after a runtime resume by
    ensuring we wait long enough,
  - avoid returning a false error form the buffer setup callbacks,
  - add enough wait time to get the correct conversion,
  - remove an unnecessary config register update,
  - add a helper to set conversion mode reducing repeated boilerplate,
  - use devm_iio_triggered_buffer_setup to simplify error and remove
    paths,
  - use iio_device_claim_direct_mode instead of opencoding the same.
* ak8974

* apds9300
  - constify the i2c_device_id.

    on going throughout the kernel.
* st_accel
  - fix drdy configuration for a load of accelerometers that only have
    the int1 line.  Fix is unimportant as presumably no deviec tree actually
    used the non existent hardware line.
* st_pressure
  - fix drdy configuration for LPS22HB and LPS25H by dropping int2 support
    as they don't have this. Fix is unimportant as presumably no device tree
    actually used the non existent hardware line.

The ADS1015 device have two operating modes, continuous conversion mode
and single-shot mode.  This driver assumes that the continuous conversion
mode is selected by runtime resume callback when the ADC result is
requested.

If CONFIG_PM is disabled, the device is always in the default single-shot
mode and no one begins a single conversion.  So the conversion register
doesn't contain valid ADC result.  Fix it by changing the continuous mode
in probe function.

It breaks the current data rate setting if the different channel's sampling

staging: lustre: mgc: fix potential use after free in error path

The config_log_add() function first calls config_log_put() with the
variable 'cld' and then jumps to label 'out_cld', which will call
the same function with the same 'cld' variable. However, at this
point, 'cld' might have been already freed by the first invocation
of config_log_put(). Even if we remove the invocation at that point,
we will still get into trouble. This is because, in the error path,
just below the label 'out_cld', we try to put 'params_cls' and
'sptlrpc_cld', which might also have been freed by config_log_put().

The point is that, config_llog_data::cld_sptlrpc and
config_llog_data::cld_params members are assigned at the beginning
of this function.

To avoid this, do not call config_log_put() inside the else block,
immediately jump to 'out_cld' instead. Moreover, remove assignments
to config_llog_data::cld_sptlrpc and config_llog_data::cld_params at
the beginning, since we already assign them below in the function
with 'cld_lock' held.

As an additional benefit, code size gets smaller.

Also, if a partner is not PD capable, it does not really make sense to send

Trigger the role swap from data role change requests and introduce new
state PORT_RESET and use it to solve the problem. This new state is
mostly identical to ERROR_RECOVERY, only it does not cause a pending

Role swap requests fail unless the current role is either SRC_READY or

immediately enter READY state after reporting a successful role swap
to user space. However, on power role changes, the role swap is currently
reported as successful while power negotiation is still in process.
User space does not know this, and may request another role swap
immediately after a power role swap is reported to be complete.
This second role swap will fail with -EAGAIN.

To fix the problem, report role swap completion after power negotiation
is complete and the state machine enters SRC_READY or SNK_READY state.
This is better anyway since it captures errors due to failed power
negotiations. It also simplifies the code since the number of calls
