watchdog: max77620_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/max77620_wdt.ko | grep alias
$
After this patch:
modinfo drivers/watchdog/max77620_wdt.ko | grep alias
alias: platform:max77620-watchdog
