From: Bjorn Helgaas Date: Mon, 28 Apr 2008 22:34:06 +0000 (-0600) Subject: PNP: remove more pnp_resource_table arguments X-Git-Tag: v2.6.26-rc1~101^2^2~36 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4ab55d8d4f7b910c4c60e0f8ff70d0dfdd484f02;p=linux-2.6 PNP: remove more pnp_resource_table arguments 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.
