From 812318a094d0715194d9f686b22ee67e7dc59d93 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Wed, 21 Feb 2018 11:44:26 +0100 Subject: [PATCH] rtc: cmos: let the core handle invalid time Setting the rtc to a valid time when the time is invalid is a bad practice, because then userspace doesn't know it shouldn't trust the RTC.
