| |
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-ath79.ko | grep alias alias: platform:ath79-spi
After this patch:
$ modinfo drivers/spi/spi-ath79.ko | grep alias alias: platform:ath79-spi alias: of:N*T*Cqca,ar7100-spiC* alias: of:N*T*Cqca,ar7100-spi
