If the driver is built as a module, autoload won't work because the module

Export the module alias information using the MODULE_DEVICE_TABLE() macro.
Before this patch:
$ modinfo drivers/hwmon/scpi-hwmon.ko | grep alias

After this patch:
$ modinfo drivers/hwmon/scpi-hwmon.ko | grep alias
alias: of:N*T*Carm,scpi-sensorsC*
alias: of:N*T*Carm,scpi-sensors

Applied.
