Message-ID: <1414634299-18078-1-git-send-email-Ying.Liu@freescale.com> Date: Thu, 30 Oct 2014 09:58:19 +0800 From: Liu Ying <Ying.Liu@...escale.com> To: <gregkh@...uxfoundation.org> CC: <linux-kernel@...r.kernel.org> Subject: [PATCH v2] devres: Improve grp->id setting logics in devres_open_group() Instead of setting grp->id directly with a temporary value and then changing it if a certain condition meets, we may check the condition first and then decide which value should be set to grp->id. This may save two lines of code and potentially reduces a writing operation.
