hwmon: (dme1737) probe all addresses
This patch adds a module load parameter to enable probing of non-standard LPC addresses 0x162e and 0x164e when scanning for supported ISA chips. Signed-Off-By: Juerg Haefliger <juergh at gmail.com> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
