From 95ab3669f7830682c7762e9c305a0c1dd44454cc Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 28 Apr 2008 16:34:26 -0600 Subject: [PATCH] PNP: remove PNP_MAX_* uses Remove some PNP_MAX_* uses. The pnp_resource_table isn't dynamic yet, but with pnp_get_resource(), we can start moving away from the table size constants.
