>From 2.1.60, PLIP does not work. It's because of the clean up of
irq2dev_map. Specifically, plip_interrupt is invoked with 2nd
argument as "struct parport *", while it expects "struct device *".
Reading lp.c, it seems for me that changing plip.c is the right
solution, like:

However, considering the consistency among other network drivers and
reading parport_share.c, I think that the intention of the field
private in struct pardevice was:

Wasn't it?
Please change plip.c or (parport_share.c and lp.c). Thanks.
