| |
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/mtd/nand/omap2_nand.ko | grep alias alias: platform:omap2-nand
After this patch:
$ modinfo drivers/mtd/nand/omap2_nand.ko | grep alias alias: platform:omap2-nand alias: of:N*T*Cti,omap2-nandC* alias: of:N*T*Cti,omap2-nand
