| |
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/mfd/fsl-imx25-tsadc.ko | grep alias alias: platform:mx25-tsadc
After this patch:
$ modinfo drivers/mfd/fsl-imx25-tsadc.ko | grep alias alias: platform:mx25-tsadc alias: of:N*T*Cfsl,imx25-tsadcC* alias: of:N*T*Cfsl,imx25-tsadc
