gpio: ath79: Fix module autoload

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/gpio/gpio-ath79.ko | grep alias $ After this patch: $ modinfo drivers/gpio/gpio-ath79.ko | grep alias alias: of:N*T*Cqca,ar9340-gpioC* alias: of:N*T*Cqca,ar9340-gpio alias: of:N*T*Cqca,ar7100-gpioC* alias: of:N*T*Cqca,ar7100-gpio Signed-off-by: Javier Martinez Canillas <[email protected]> Acked-by: Aban Bedel <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
