From f4282a4303dc7eada2543ea9b87e2b9bdec9344b Mon Sep 17 00:00:00 2001 From: Alexandre Belloni <alexandre.belloni@bootlin.com> Date: Wed, 28 Feb 2024 00:04:16 +0100 Subject: [PATCH] rtc: ds1511: drop useless checks The RTC core will always pass a valid rtc_tm, it is unnecessary to check the validity of its members, especially with an open coded version of rtc_valid_tm().
