From: YoungJun Cho Date: Mon, 26 May 2014 08:17:17 +0000 (+0200) Subject: drm/exynos: ipp: rename cmd_lock to lock X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=4e4fe5546de3cfd97921f24d9df4c4f323941729;p=openwrt%2Fstaging%2Fblogic.git drm/exynos: ipp: rename cmd_lock to lock The ippdrv->cmd_list requires cmd_lock. So renames cmd_lock to lock for context.
