| |
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/power/reset/at91-reset.ko | grep alias $
After this patch:
$ modinfo drivers/power/reset/at91-reset.ko | grep alias alias: of:N*T*Catmel,sama5d3-rstcC* alias: of:N*T*Catmel,sama5d3-rstc alias: of:N*T*Catmel,at91sam9g45-rstcC* alias: of:N*T*Catmel,at91sam9g45-rstc alias: of:N*T*Catmel,at91sam9260-rstcC* alias: of:N*T*Catmel,at91sam9260-rstc alias: platform:at91-sam9g45-reset alias: platform:at91-sam9260-reset
