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

virtual patch

identifier iioinfo;
identifier wecfunc;

 static const struct iio_info iioinfo = {
        ...,
        .write_event_config =

 wecfunc

 &wecfunc
),
        ...,
 };

 state) {
  ...
 }

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.

Hi Julien,

I went through these by hand.  There are somewhere maybe it is worth
passing booleans down into leaf functions and only convert to int
right at the end (for a field write) but I don't think we care.
The cases here are more of the variety of converting a bool to an int
to use it as a bool (like the ones you clear up later in this series).

Neither is wrong, just inefficient, so applied and pushed out as testing
for 0-day to take a look.
Fingers crossed nothing got missed!

Jonathan

This passes the state variable into fxls8962af_event_setup() as an integer
and uses it as a boolean.  Might as well be bool all the way.

This one could do with a follow up as the state variable is passed as an integer
to another function that then uses it as a bool.
