One nasty very old crash around polling for buffers that aren't there
- though that can only cause effects on drivers that support events
but not buffers.
* buffer / kfifo handling in the core.
- Check there is a buffer and return 0 from poll directly if there
isn't. Poll doesn't make sense in this circumstances, but best to close
the hole.
* ad5933
- Change the marked buffer mode to a software buffer as the meaning of
the hardware buffer label has long since changed and this uses a front
end software buffer anyway.
* ad7192
- Fix the fact the external clock frequency was only set when using the
internal clock which was less than helpful.
* adis_lib
- Initialize the trigger before requesting the interrupt. Some newer
parts can power up with interrupt generation enabled so ordering now
matters.
* aspeed-adc
- Fix an errror handling path as labels and general ordering were wrong.
* srf08
- Fix a link error due to undefined devm_iio_triggered_buffer_setup.
* stm32-adc
- Fix error handling unwind squence in stm32h7_adc_enable.
