Subject: [PATCH 16/17] rtc: rx8010: remove RTC_VL_CLR handling
Date: Sat, 14 Dec 2019 23:02:58 +0100 [thread overview]
Message-ID: <20191214220259.621996-17-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20191214220259.621996-1-alexandre.belloni@bootlin.com>
Remove RTC_VL_CLR handling because it is a disservice to userspace as it
removes the important information that the RTC data is invalid. This may
lead userspace to set an invalid system time later on.
