just added this in(as a test), and the retval warning still shows up.
with the last post I just added a printk was that legit, and if so what

What's the full warning? Seems like printing the value should have

this is the warning messg after applying yinghai's patch:
CC drivers/pci/setup-bus.o
drivers/pci/setup-bus.c: In function
'pci_assign_unassigned_bridge_resources':
drivers/pci/setup-bus.c:868:6: warning: variable 'retval' set but not used
if I add a printk then gcc is content.. patch below, but not the best at
creating printk's(the whole % thing messes me up) but here goes:
