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

voltage as there is no way to obtain this on ACPI currently.
Cleanup and fixes:

This driver assumes that the device is operating in the continuous
conversion mode which performs the conversion continuously. So this driver
inserts a wait time before reading the conversion register if the

Currently, the wait time is only the period required for a single
conversion that is calculated as the reciprocal of the sampling frequency.
However we also need to wait for the the previous conversion to complete.
Otherwise we probably get the conversion result for the previous
configuration when the sampling frequency is lower.

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.

staging: typec: tcpm: explicit_contract is always established
While in SNK_READY state, the explicit_contract seems to be
set to true irrespective of whether an explicit contract
was established for the current connection. TCPM also seems
to report the pwr_opmode as TYPEC_PWR_MODE_PD always once
the port gets into SNK_READY state. This isn't completely
true as port gets into the SNK_READY state for non-pd
type-c ports as well.
This patch sets the explicit_contract flag only when
the PS_READY message is received and the vbus has been
detected by the port controller.

staging: speakup: fix async usb removal
When an external USB synth is unplugged while the module is loaded, we
get a null pointer deref. This is because the tty disappears while
speakup tries to use to to communicate with the synth. This patch fixes
it by checking tty for null before using it. Since tty can become null
between the check and its usage, a mutex is introduced. tty usage is
now surrounded by the mutex, as is the code in speakup_ldisc_close which
sets the tty to null. The mutex also serialises calls to tty from
speakup code.
In case of tty being null, this sets synth->alive to zero and restarts
ttys in case they were stopped by speakup.

platform_get_irq() returns an error code, but the dim2_hdm driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.
Also, notice that platform_get_irq() no longer returns 0 on error:
