This v2 bases on v6.12-rc1 + commit 64612ec9b909 ("iio: adc: ad7124: Disable all channels at probe time") which is already in next. Changes since v1: - reword commit log of patch #1 to honestly tell that the maximal number of logical channels is a limitation of the current driver implementation (and not one imposed by hardware). - Make the driver explicitly fail to load if > 16 channels are defined. v1 only limited the maximal channel address which then later yielded a probe failure on the first channel exeeding that maximum. - in patch #2 fix "passing zero to 'dev_err_probe'" as reported by smatch + Dan Carpenter. - Fix my address in patch #2's S-o-b trailer.
