| |
Linus, here is a patch from Adam J. Richter to add the tiny kernel hook for device-id based parport device driver module loading, as well as an example usage in lp.c. (The code for making use of it is already in modutils.)

* include/linux/parport.h: Declare parport_device_id. * drivers/char/lp.c: Use it as MODULE_DEVICE_TABLE.
