Hello,

this is v2 of the series fixing https://bugs.debian.org/794266.

The only change compared to (implicit) v1 is that reading out a disabled
alarm is fixed. When the alarm is disabled the respective register is
shadowed with the result is that the reported alarm time is 45:85:0
because both hour and minute byte are read as 0xff and bcd2bin(0x3f) and
bcd2bin(0x7f) are 45 and 85 respectively.

The new behaviour is to only set .enabled =3D 0 and return. Not 100% sure
this is the right thing, though. The only alternative is to enable alarm
and read out a time, but that might have the side effect to trigger an
unwanted alarm, so I didn't chose this way.

Best regards
Uwe
