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 Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> --- drivers/mtd/nand/omap2.c | 1 + 1 file changed, 1 insertion(+)
