Should this be in spi_nor_register_locking_ops(), too? I.e.

void spi_nor_register_locking_ops() {
     if (!nor->params->locking_ops)
         return;
..
}

I don't have a strong opinion on that so far. I just noticed because
I put the check into spi_nor_otp_init() for my OTP series. They should
be the same though.
