I tend to code if (!strcmp(option, "hte")) but taste differs.

Pity we don't have match_string() API in a libc or somewhere in the user space.
Allows to avoid such mistakes at once.

We have several instances of such string parsing in tools/ in libgpiod
so feel free to add and use it. You can even port linux code verbatim
- libgpiod is GPL after all. :)
