hwmon: (lm78) Add individual alarm files
Add individual alarm files to the lm78 driver, these are needed by the next version of libsensors. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>

59In addition to the alarms described above, there are a couple of additional
60ones. There is a BTI alarm, which gets triggered when an external chip has
61crossed its limits. Usually, this is connected to all LM75 chips; if at
62least one crosses its limits, this bit gets set. The CHAS alarm triggers
63if your computer case is open. The FIFO alarms should never trigger; it
64indicates an internal error. The SMI_IN alarm indicates some other chip
65has triggered an SMI interrupt. As we do not use SMI interrupts at all,
66this condition usually indicates there is a problem with some other
67device.
