From what I understand, the patch is correct but the description may be
wrong?

AFAIU the patch adds the slave event I2C_SLAVE_READ_PROCESSED to the
case when the last byte was transferred. We as the client got a NAK from
the controller. However, the byte WAS processed, so the event is ok and
not a dummy?
