Message-Id: <20160802103855.18883-1-baolex.ni@intel.com> Date: Tue, 2 Aug 2016 18:38:55 +0800 From: Baole Ni <baolex.ni@...el.com> To: rjw@...ysocki.net, len.brown@...el.com, pavel@....cz, gregkh@...uxfoundation.org, hpa@...or.com, x86@...nel.org Cc: linux-pm@...r.kernel.org, linux-kernel@...r.kernel.org, chuansheng.liu@...el.com, baolex.ni@...el.com Subject: [PATCH 0077/1285] Replace numeric parameter like 0444 with macro I find that the developers often just specified the numeric value when calling a macro which is defined with a parameter for access permission. As we know, these numeric value for access permission have had the corresponding macro, and that using macro can improve the robustness and readability of the code, thus, I suggest replacing the numeric parameter with the macro.
