From 9fb7aa7501b0293b44405f1b8053727266436dc6 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Wed, 21 Feb 2018 11:23:19 +0100 Subject: rtc: spear: stop validating rtc_time in .set_time and .set_alarm The RTC core is always validating the rtc_time struct before calling .set_time or .set_alarm. It is not necessary to do it again.
