[ Upstream commit a223770bfa7b6647f3a70983257bd89f9cafce46 ]
CONFIG_WATCHDOG_PRETIMEOUT_GOV build symbol adds watchdog_pretimeout.o object to watchdog.o, the latter is compiled only if CONFIG_WATCHDOG_CORE is selected, so it rightfully makes sense to add it as a dependency.
The change fixes the next compilation errors, if CONFIG_WATCHDOG_CORE=n and CONFIG_WATCHDOG_PRETIMEOUT_GOV=y are selected:
drivers/watchdog/pretimeout_noop.o: In function `watchdog_gov_noop_register': drivers/watchdog/pretimeout_noop.c:35: undefined reference to `watchdog_register_governor' drivers/watchdog/pretimeout_noop.o: In function `watchdog_gov_noop_unregister': drivers/watchdog/pretimeout_noop.c:40: undefined reference to `watchdog_unregister_governor'
drivers/watchdog/pretimeout_panic.o: In function `watchdog_gov_panic_register': drivers/watchdog/pretimeout_panic.c:35: undefined reference to `watchdog_register_governor' drivers/watchdog/pretimeout_panic.o: In function `watchdog_gov_panic_unregister': drivers/watchdog/pretimeout_panic.c:40: undefined reference to `watchdog_unregister_governor'
