Subject: [PATCH] pch_uart: Set PCIe bus number using probe parameter
Date: Wed, 20 Jul 2011 20:17:49 +0900 [thread overview]
Message-ID: <1311160669-3927-1-git-send-email-tomoya-linux@dsn.okisemi.com> (raw)
Currently, PCIe bus number is set as fixed value "2".
However, PCIe bus number is not always "2".
This patch sets bus number using probe() parameter.
