We have a couple of changes that apply to large sets of drivers, so
I have grouped those to keep this short.
There are a few late breaking fixes in here that can wait for the
merge window.

Features
--------
* adxrs290
- Add triggered buffer support and expose data ready signal as a possible
trigger. Includes updating bindings.
- Add debugfs hooks for register access.
* mlx90632
- Add a clear user interface to override the measured ambient temperature.
* vl53l0x

Cleanups and minor fixes

Replace mlock with local lock:

* exynos-adc
* fls-imx25-gcq
* stm32-dac
devm use to simplify probe error handling and remove functions.
* adis16201

* adis16136
* adis16260
* adis16400
* adis16460
* adis16480
* adis library - drop unused adis_setup_buffer_and_trigger()
of_match_ptr removal and incorrect ACPI binding removal
of_match_ptr() rarely makes sense in an IIO driver as space saving
is trivial and it breaks ACPI PRP0001 based instantiation.
Mostly this series is about removing examples that get copied into new
drivers.

Since there was a recently discovered issue with these locks, it probably
makes sense to cleanup the code a bit, to prevent it from being used as an
example/reference.
This change moves the lock only where it is explicitly needed to protect
resources from potential concurrent accesses.
It also reworks the switch statements to do direct returns vs caching the
return value on a variable.

The next rework may require an unindentation of a code block in
ad5592r_read_raw(), which would make review a bit more difficult.
This change unindents the code block for reading the scale of the
non-temperature channels.

struct iio_chan_spec_ext_info shared element is of type
enum iio_shared_by, not boolean. It's like the enum value
will for IIO_SHARED_BY_TYPE == 1 == true, hence no actual
problem has been observed.

There are 2 exit paths where the lock isn't held, but try to unlock the
mutex when exiting. In these places we should just return from the
function.
A neater approach would be to cleanup the ad5592r_read_raw(), but that
would make this patch more difficult to backport to stable versions.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.

This was partially removed when the mlock cleanup was done. Only one more
call is left in the ad5592r_alloc_channels() function.
This one is simple. We just need to pass the iio_dev object and get the
state via iio_priv().
