Added trigger buffer support to read continuous acceleration
and temperature data from device with data ready interrupt which
is mapped to INT1 pin.

This is a conversion to device-managed by using devm_iio_device_register()
inside probe function. Previously the bma400 was not put into power down
mode in some error paths in probe where it now is, but that should cause
no harm.
The dev_set_drvdata() call, bma400_remove() function and hooks in the I2C
and SPI driver struct is removed as devm_iio_device_register() function is
used to automatically unregister on driver detach.

Here is the big set of char/misc and other small driver subsystem
updates for 5.18-rc1.
Included in here are merges from driver subsystems which contain:
- iio driver updates and new drivers
- fsi driver updates
- fpga driver updates
- habanalabs driver updates and support for new hardware
- soundwire driver updates and new drivers
- phy driver updates and new drivers
- coresight driver updates
- icc driver updates
Individual changes include:
- mei driver updates
- interconnect driver updates
- new PECI driver subsystem added
- vmci driver updates
- lots of tiny misc/char driver updates
There will be two merge conflicts with your tree, one in MAINTAINERS
which is obvious to fix up, and one in drivers/phy/freescale/Kconfig
which also should be easy to resolve.
All of these have been in linux-next for a while with no reported
problems.

move the core bma400 functions into a bma400 specific namespace
and import that into the two bus modules.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

When an i2c or spi driver's remove function returns a non-zero error
code nothing happens apart from emitting a generic error message. Make
this error message more device specific and return zero instead in the
remove callbacks. As the return value of bma400_remove() is unused then,
change the function to not yield a return value.
