freebsd/sys/pci/es1370.c
Peter Wemm 579f45fa60 Simplify the COMPAT_PCI_DRIVER/DATA_SET hack. We can add: 
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it.  Driver writers can do
this if it's not defined.  (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)
