Subject: [PATCH v2 0/2] iio: adc: ad7124: Implement input validation

Hello,

(implicit) v1 of the series can be found at
https://lore.kernel.org/linux-iio/20241108181813.272593-4-u.kleine-koenig@baylibre.com.
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.

Uwe Kleine-König (2):
  iio: adc: ad7124: Don't create more channels than the driver can
    handle
  iio: adc: ad7124: Refuse invalid input specifiers
