What kind of other error code you may expect and why they are not
considered as no error?
According to documentation, kstrtobool can only fail with -EINVAL.
See:
https://elixir.bootlin.com/linux/v4.18-rc5/source/lib/kstrtox.c#L332
That's correct. So, what do you want to show by explicitly mentioned
an error code in the condition?
So you mean I should check for negative values instead of specific
error, right?
Thanks
Giulio
