gpio: ts4800: 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-ts4800.ko | grep alias $ After this patch: $ modinfo drivers/gpio/gpio-ts4800.ko | grep alias alias: of:N*T*Ctechnologic,ts4800-gpioC* alias: of:N*T*Ctechnologic,ts4800-gpio Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
