it should call one of the {devm_}iio_triggered_buffer_setup() or

Some devices that want to make use of the DMA buffer might need to do
something special, like write a register when the buffer is enabled.
Extend the API to allow those drivers to provide their own buffer ops.

Add output buffer support to the kfifo buffer implementation.
The implementation is straight forward and mostly just wraps the kfifo
API to provide the required operations.

Oddly enough the noop function is an int-return. This one seems to be void.
This change converts it to int, because we want to change how groups are
registered. With that change this function could error out with -ENOMEM.

Since we'll also open some chardevs via anon inodes, we can pass extra
buffers in that function by assigning another object to the
