watchdog: bcm7038_wdt: 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/watchdog/bcm7038_wdt.ko | grep alias $ After this patch: $ modinfo drivers/watchdog/bcm7038_wdt.ko | grep alias alias: of:N*T*Cbrcm,bcm7038-wdtC* alias: of:N*T*Cbrcm,bcm7038-wdt Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
