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
