Date: Wed, 28 Feb 2024 00:04:16 +0100 From: alexandre.belloni@...tlin.com To: Alexandre Belloni <alexandre.belloni@...tlin.com> Cc: linux-rtc@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 01/12] rtc: ds1511: drop useless checks From: Alexandre Belloni <alexandre.belloni@...tlin.com> 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().
