Hello,
This series update the write_event_config callback signature to use
a boolean instead of an int for state variable. iio_ev_state_store
is actually using kstrtobool to check user input, then gives the
converted boolean value to write_event_config.
First, fix the write_event_config callbacks from iio drivers that are
checking state input, or that are converting state to bool. This is
useless code, then update signature.
This patch has been partially written using coccinelle with the
following script:
$ cat iio-bool.cocci
// Options: --all-includes
virtual patch
@c1@
identifier iioinfo;
identifier wecfunc;
@@
static const struct iio_info iioinfo = {
...,
.write_event_config =
(
wecfunc
|
&wecfunc
),
...,
};
@@
identifier c1.wecfunc;
identifier indio_dev, chan, type, dir, state;
@@
int wecfunc(struct iio_dev *indio_dev, const struct iio_chan_spec *chan, enum iio_event_type type, enum iio_event_direction dir,
-int
+bool
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.

Changes in v2:
- removed commits that were already applied
- added new commits to fix comments from Jonathan Cameron: cleanup code
in few callbacks to update driver internal function signature to also use
bool for state and update the driver internal state variable to bool.
- few minor fixes along the way on different driver
- Link to v1: https://lore.kernel.org/r/20241024-iio-fix-write-event-config-signature-v1-0-7d29e5a31b00@xxxxxxxxxxxx
