Subject: [PATCH AUTOSEL 6.12 181/486] rtc: ds1307: stop disabling alarms on probe
From: Alexandre Belloni <alexandre.belloni@...tlin.com>
[ Upstream commit dcec12617ee61beed928e889607bf37e145bf86b ]
It is a bad practice to disable alarms on probe or remove as this will
prevent alarms across reboots.
