From: Greg Ungerer Date: Fri, 18 Sep 2009 00:29:12 +0000 (+1000) Subject: m68knommu: remove un-used mcfsmc.h X-Git-Tag: v2.6.35-rc1~267^2~3 X-Git-Url: http://bbs.cooldavid.org/git/?a=commitdiff_plain;h=f606aee2e0a37013cf2a8a28d7ed089d7c31d55a;p=net-next-2.6.git m68knommu: remove un-used mcfsmc.h Remove the un-used mcfsmc.h. All ColdFire platforms that use SMC ethernet devices are platform enabled to use the smc91x driver.
