From: Bjorn Helgaas Date: Mon, 28 Apr 2008 22:34:22 +0000 (-0600) Subject: PNP: pass resources, not indexes, to pnp_check_port(), et al X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f5d94ff014cb7e6212f40fc6644f3fd68507df33;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git PNP: pass resources, not indexes, to pnp_check_port(), et al The caller already has the struct resource pointer, so no need for pnp_check_port(), pnp_check_mem(), etc., to look it up again.
