Subject: [PATCH 0/4] iio/adc-joystick: buffer data parsing fixes

Hi all,

this patch set fixes the way channel data is being parsed in the
adc-joystick driver. To achieve that, it also introduces helpers in the
IIO subsystem. As a side effect of those changes, a bug in ingenic-adc
has been exposed, which this patch set promptly rectifies.

Tested on GCW Zero (by me) and on Anbernic RG350 (by Paul).

Chris:
As you have originally reported the issue, would you be able to test
the above changes on your setup (Odroid Go Advance, was it)?

Artur Rojek (4):
  iio/adc: ingenic: fix channel offsets in buffer
  iio: add iio_channel_cb_get_iio_buffer helper
  iio: add helper function for reading channel offset in buffer
  input: joystick: Fix buffer data parsing
