[PATCH v2 2/2] iio: light: stk3310: Update includes to match IWYU

[Rafael G. Dias]

Clean up the included headers in stk3310.c according to the
Include-What-You-Use (IWYU) tool. Remove the generic <linux/kernel.h>
header and add explicit dependencies to improve compilation accuracy.

Try not to send follow-up patches at least 24 hours,
let them sit so others can look over them.

Otherwise LGTM.

https://sashiko.dev/#/patchset/20260428161339.1187956-1-rafael.guimaraes.dias%40usp.br
Had a few comments.  I added asm/byteorder.h and linux/sysfs.h.

Maybe we could argue the sysfs.h one will always be included by
iio/sysfs.h but I think it's better to explicitly include it
for struct attribute_group and similar.

The asm/byteorder.h is simpler one as that should definitely be here.

Anyhow, tweaked whilst applying and applied to the testing branch of
iio.git.

However, do slow down a bit as Joshua suggested - I'd generally
suggest a week between first version and second, but I am a bit
more relaxed on this for students and new submitters doing fairly
simple patches.

Thanks,

Jonathan

Re: [PATCH v2 2/2] iio: light: stk3310: Update includes to match IWYU

[Rafael Guimaraes Dias]

(Resending as plain text for the mailing list. Apologies for the
duplicate to those who already received it).

Hi Jonathan and Joshua,

Thank you very much for the guidance and for the time you took to
review this patchset.

Thank you, Jonathan, for making the final tweaks with asm/byteorder.h
and linux/sysfs.h before applying it. I completely understand your
point regarding the explicit inclusion for attribute_group.

I also appreciate the advice about slowing down between versions. I
will definitely keep that in mind and wait longer before sending out
updated versions in my future contributions.

Best regards, Rafael G. Dias

In most cases we assume errno (but strictly speaking it's asm/errno) is
included by err.h. Double check if there are no codes >= 512 are in use in the
driver. If no, drop errno.h.
