Subject: PCI: use resource_size() everywhere.
X-Git-Tag: v2.6.28-rc1~77^2~15
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=022edd86d7c864bc8fadc3c8ac4e6a464472ab05;p=linux-2.6-omap-h63xx.git

PCI: use resource_size() everywhere.

This is a cleanup that replaces the resource calculation formula with
resource_size().
