rtc: pcf2127: fix reading uninitialized value on RTC_READ_VL ioctl 2015-11-08T13:12:27+00:00 Uwe Kleine-König u.kleine-koenig@pengutronix.de 2015-10-02T09:17:19+00:00 f97cfddc886bc8f9d4302447f8773239bed854c1 The flag reported on the RTC_READ_VL ioctl is only initialized when the date is read out. So the voltage low value doesn't represent reality but the status at the time the date was read (or 0 if the date was not read yet). Moreover when userspace requests a value via an ioctl there is no added benefit to also make a prosa representation of this (and other) values appear in the kernel log so remove the calls to dev_info and the driver data members to track their state.

Battery may be low (usually below 2V5 threshold) but the date may be anyway correct (typically date is unreliable when input voltage is below 1V2).
