| |
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 OF and I2C device ID table entries as module aliases, using the MODULE_DEVICE_TABLE() macro.
Before this patch:
$ modinfo drivers/staging/typec/fusb302/fusb302.ko | grep alias $
After this patch:
$ modinfo drivers/staging/typec/fusb302/fusb302.ko | grep alias alias: of:N*T*Cfcs,fusb302C* alias: of:N*T*Cfcs,fusb302 alias: i2c:typec_fusb302
