From: Kenji Kaneshige Date: Thu, 9 Aug 2007 23:09:33 +0000 (-0700) Subject: pciehp: remove DBG_XXX_ROUTINE X-Git-Tag: v2.6.24-rc1~1393^2~32 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=c8426483776d913c5bdc3d698a7633496a885b78;p=linux-2.6-omap-h63xx.git pciehp: remove DBG_XXX_ROUTINE This patch removes DBG_ENTER_ROUTIN, DBG_LEAVE_ROUTINE and related code, which seem no longer needed.
