| |
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-jcore.ko | grep alias alias: platform:jcore_spi
After this patch:
$ modinfo drivers/spi/spi-jcore.ko | grep alias alias: platform:jcore_spi alias: of:N*T*Cjcore,spi2C* alias: of:N*T*Cjcore,spi2
