This changes the way this code works. You release the descriptor here,
it returns to the driver and can be re-requested by someone else. Its
value is also not guaranteed to remain as "active". Is this what you
want?

Good point. Is it enough to not call gpiod_put() at the end or is it necessary
to use a static gpio_desc instead of a local one?

Technically it's enough to not put it. It will live on but the
reference will be leaked and most likely this will be reported by
kmemleak. So static desc would make more sense.
