The new driver supports more devices, 792 and makes it easier to add support for new devices. 793 794 An adapter type parameter is now mandatory.

This 817 might be preferred on embedded systems where wasting memory for 818 the clean but heavy parport handling is not an option. The 819 drawback is a reduced portability and the impossibility to 820 daisy-chain other parallel port devices. 821 822 Don't say Y here if you said Y or M to i2c-parport.
