Bug 21087

Summary:	ed driver incorrectly fails probe for ISA HP PCLAN+
Product:	Base System	Reporter:	buchanan <buchanan>

Description buchanan 2000-09-07 06:30:01 UTC

ed_probe_HP_pclanp() in /sys/dev/ed/if_ed.c returns ED_HPP_IO_PORTS (32)
after a successful probe, instead of zero as device_probe_child() in
/sys/kern/subr_bus.c expects.  device_probe_child() then (silently!)
fails to attach the device.  Returning ED_HPP_IO_PORTS (the number of
I/O ports occupied by the device) appears to be behavior from the v3
driver that was missed in building the v4 driver.

Fix: 

Change the last line of ed_probe_HP_pclanp() to return zero.
How-To-Repeat: Install/configure HP PCLAN+ card; boot 4.1-RELEASE install media; 
configure ed0 device appropriately; observe that ed0 is not detected.
Compare with 3.4-RELEASE behavior.
