hwmon: (scpi) Fix module autoload
commit 13edb767aa609b6efb7c0c2b57fbd72a6ded0eed upstream.
If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding 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
