Message-Id: <20210208021732.21856-1-samirweng1979@163.com> Date: Mon, 8 Feb 2021 10:17:32 +0800 From: samirweng1979 <samirweng1979@....com> To: davem@...emloft.net, alex.dewar90@...il.com Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, wengjianfeng <wengjianfeng@...ong.com> Subject: [PATCH] nfc: st-nci: Remove unnecessary variable From: wengjianfeng <wengjianfeng@...ong.com> The variable r is defined at the beginning and initialized to 0 until the function returns r, and the variable r is not reassigned.Therefore, we do not need to define the variable r, just return 0 directly at the end of the function.
