| Subject: [PATCH] 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 |
