This change converts the driver to register via devm_iio_device_register().
The regulator disable is moved on a devm_add_action_or_reset() hook.
And the spi_set_drvdata() isn't required anymore.
And finally, the ads8344_remove() can be removed as well.

Convert the driver to platform specific structures. This means:
- create a register layout struct that will hold offsets for registers
- create a platform struct that will hold platform information (number of
channels, indexes for different channels and pointer to layout struct)
- convert specific macros that are platform dependent into platform variables
This step is in fact a no-op, but allows the driver to be more flexible
and for future enhancement including adding new platforms that are partly
compatible with the current driver and differ slightly in register layout
or capabilities for example.

If there are no channels defined in the devicetree, there's no point in
probing the device. We were actually requesting a zero sized 'kmalloc'
array but since we were not touching the ZERO_SIZE_PTR afterwards,
nothing bad was actually happening. Hence this is not really a fix but
rather an improvement.

The bindings file for this driver is defining the property as 'reg' but
the driver was reading it with the 'num' name. The bindings actually had
the 'num' property when added in
commit ea52c21268e6 ("dt-bindings: iio: dac: Add docs for AD5770R DAC")
and then changed it to 'reg' in
commit 2cf3818f18b2 ("dt-bindings: iio: dac: AD5570R fix bindings errors").
However, both these commits landed in v5.7 so the assumption is
that either 'num' is not being used or if it is, the validations were not
done.
Anyways, if someone comes back yelling about this, we might just support
both of the properties in the future. Not ideal, but that's life...

The idea behind it, is that all devm_ calls in ST sensors are bound to the
parent device object.
However, the reference to that object is kept on both the st_sensor_data
struct and the IIO object parent (indio_dev->dev.parent).
This change only adds a bit consistency and uses the reference stored on
indio_dev->dev.parent, to enforce the assumption that all ST sensors' devm_
calls are bound to the same reference as the one store on st_sensor_data.

This change converts the st_sensors_power_enable() function to use
devm_add_action_or_reset() handlers to register regulator_disable hooks for
when the drivers get unloaded.
The parent device of the IIO device object is used. This is based on the
assumption that all other devm_ calls in the ST sensors use this reference.
This makes the st_sensors_power_disable() un-needed.
Removing this also changes unload order a bit, as all ST drivers would call
st_sensors_power_disable() first and iio_device_unregister() after that.

Up until commit ea7e586bdd331 ("iio: st_sensors: move regulator retrieveal
to core") only the ST pressure driver seems to have had any regulator
disable. After that commit, the regulator handling was moved into the
common st_sensors logic.
In all instances of this regulator handling, the regulators were disabled
before unregistering the IIO device.
This can cause issues where the device would be powered down and still be
available to userspace, allowing it to send invalid/garbage data.
This change moves the st_sensors_power_disable() after the common probe
functions. These common probe functions also handle unregistering the IIO
device.

This driver supports devices with 14-bit and 16-bit sample sizes.
This implies different SPI transfer lengths which are not always handled
properly by some SPI controllers.
To work around this limitation, define a big endian buffer used to split
the buffer into two 8-bit messages in the event that the controller
doesn't support 14-bit or 16-bit transfers.
A separate buffer is introduced here to avoid performing operations on
types of different endianness.
Since all transfers use the same bits_per_word value, move that logic to
the probe function, and let transfers default to the value defined in
the struct spi_device.

strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. So, remove all the uses and add
devm_kstrdup() or devm_kasprintf() instead.
Also, modify the "for" loop conditions to clarify the access to the
st->orientation.rotation buffer.
This patch is an effort to clean up the proliferation of str*()
functions in the kernel and a previous step in the path to remove
the strcpy function from the kernel entirely [1].

"cifs/smb3 updates:
- DFS reconnect fix
- begin creating common headers for server and client
- rename the cifs_common directory to smbfs_common to be more
consistent ie change use of the name cifs to smb (smb3 or smbfs is
more accurate, as the very old cifs dialect has long been
superseded by smb3 dialects).
In the future we can rename the fs/cifs directory to fs/smbfs.
This does not include the set of multichannel fixes nor the two
deferred close fixes (they are still being reviewed and tested)"

It adds a new ioctl, but we are still not using that to generate tables
for 'perf trace', so no changes in tooling.
