It will be a NACK from me.

This patch and other patches removing PARPORT_MODE_PCSPP will break
userspace code.
On my system, I have:
$ cat /proc/sys/dev/parport/parport0/modes
PCSPP,TRISTATE

If the flag is removed then I will only get "TRISTATE", and if there
is any userspace code which checks for the mode then those
applications will stop working with an error.
