The built-in watchdog is redundant when the device has an external GPIO based hardware watchdog. And there is a conflict that both of them will attempt to register the same device entry in sysfs. This resulted in the built-in watchdog being unable to be activated. This patch explicitly disables the built-in watchdog for devices that use GPIO watchdog to fix the error: [ 1.779206] ath79-wdt 18060008.wdt: unable to register misc device, err=-16 [ 1.786355] ath79-wdt: probe of 18060008.wdt failed with error -16 Signed-off-by: Shiji Yang <yangshiji66@outlook.com> Link: https://github.com/openwrt/openwrt/pull/18395 Signed-off-by: Robert Marko <robimarko@gmail.com>
