[patch 23/55] PNP: remove pnp_resource_table from internal pnp_clean_resource_table interface

[Bjorn Helgaas]

This changes pnp_clean_resource_table() to take a pnp_dev pointer
rather than a pnp_resource_table pointer.  This reduces the visibility
of pnp_resource_table and removes an opportunity for error in the
caller.
