Date: Mon, 28 Aug 2017 12:32:39 +0530 [thread overview] Message-ID: <1503903761-21730-2-git-send-email-arvind.yadav.cs@gmail.com> (raw) In-Reply-To: <1503903761-21730-1-git-send-email-arvind.yadav.cs@gmail.com> clk_ops are not supposed to change at runtime. All functions working with clk_ops provided by <linux/clk-provider.h> work with const clk_ops. So mark the non-const clk_ops as const. Here, Function "clk_reg_prcmu" is used to initialized clk_init_data. clk_init_data is working with const clk_ops. So make clk_reg_prcmu non-const clk_ops argument as const.
