[patch 17/37] PNP: remove more pnp_resource_table arguments

Bjorn Helgaas
2008-03-26T17:08:53Z

[-- Attachment #1: pnp-remove-more-pnp_resource_table-args --]
[-- Type: text/plain, Size: 17491 bytes --]

Stop passing around struct pnp_resource_table pointers. In most cases,
the caller doesn't need to know how the resources are stored inside
the struct pnp_dev.
