[patch 35/55] PNP: pass resources, not indexes, to pnp_check_port(), et al

[Bjorn Helgaas <bjorn.helgaas@hp.com>]

[-- Attachment #1: pnp-pass-resource-to-check-functions --]
[-- Type: text/plain, Size: 4426 bytes --]

The caller already has the struct resource pointer, so no need for
pnp_check_port(), pnp_check_mem(), etc., to look it up again.
