The ISA sensor chip address is obtained by parsing the hwmon
`/sysfs` device path. The regular expression extracting the
device address will fail if the device name contains dashes and
sets the address to 0. If multiple instances of the same
board are plugged into the same system, cards can no longer be
distinguished, because their addresses will be set to 0 incorrectly.
This fix changes the address-parsing regular expression to recognize
device names with dashes.
