Have you found the current code does not work on a board you have, or
is this by code inspection?

https://elixir.bootlin.com/linux/v6.10/source/drivers/gpio/gpiolib-of.c#L687
https://elixir.bootlin.com/linux/v6.10/source/drivers/gpio/gpiolib.h#L93

See how it appends -gpio and -gpios to the name.

I also randomly check a few users of devm_gpiod_get_optional() and non
of them include the -gpio in the name, leaving the GPIO core to do it.
