Subject: PNP: add pnp_resource_type_name() helper function
X-Git-Tag: v2.6.27-rc1~1050^2~27
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9fdee4e02e3b214cde8e4f3beb6776075a3d08a7;p=linux-2.6

PNP: add pnp_resource_type_name() helper function

This patch adds a "pnp_resource_type_name(struct resource *)" that
returns the string resource type.  This will be used by the sysfs
"show resources" function and the debug resource dump function.
