Subject: PNP: pass resources, not indexes, to pnp_check_port(), et al
X-Git-Tag: v2.6.26-rc1~101^2^2~20
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f5d94ff014cb7e6212f40fc6644f3fd68507df33;p=linux-2.6

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.
