Hi Vikas, Please try to more or less follow subsystem subject conventions. It should be: clk: samsung: exynos5420: Add clk save/restore registers By the way, this patch only adds writes to registers that should be set up before suspending the system and both the subject and description should reflect this. Please be more careful when describing patches.
