[7/7] iio: fix write_event_config signature

Commit Message

Julien Stephan Oct. 24, 2024, 9:11 a.m. UTC

write_event_config callback use an int for state, but it is actually a
boolean. iio_ev_state_store is actually using kstrtobool to check user
input, then gives the converted boolean value to write_event_config.

Fix signature and update all iio drivers to use the new signature.

This patch has been partially written using coccinelle with the
following script:

$ cat iio-bool.cocci
// Options: --all-includes

 }

make coccicheck MODE=patch COCCI=iio-bool.cocci M=drivers/iio

Unfortunately, this script didn't match all files:
* all write_event_config callbacks using iio_device_claim_direct_scoped
  were not detected and not patched.
* all files that do not assign and declare the write_event_config
  callback in the same file.

iio.h was also manually updated.

The patch was build tested using allmodconfig config.
