From: Kiyoshi Ueda Date: Thu, 10 Dec 2009 23:52:26 +0000 (+0000) Subject: dm: rename dm_suspended to dm_suspended_md X-Git-Tag: upstream/snapshot3+hdmi~16136^2~17 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4f186f8bbfa92bf1a2b39f7a8674348bfdba9437;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git dm: rename dm_suspended to dm_suspended_md This patch renames dm_suspended() to dm_suspended_md() and keeps it internal to dm. No functional change.
