| |
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/spi/spi-xlp.ko | grep alias alias: acpi*:BRCM900D:*
After this patch:
$ modinfo drivers/spi/spi-xlp.ko | grep alias alias: acpi*:BRCM900D:* alias: of:N*T*Cnetlogic,xlp832-spiC* alias: of:N*T*Cnetlogic,xlp832-spi
