From ab183586ebcba3bc00ab555622c389a584a555d6 Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Tue, 12 Mar 2019 01:54:25 +0200 Subject: [PATCH] watchdog: fix compile time error of pretimeout governors [ 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' Reported-by: Kuo, Hsuan-Chi Fixes: ff84136cb6a4 ("watchdog: add watchdog pretimeout governor framework") Signed-off-by: Vladimir Zapolskiy Reviewed-by: Guenter Roeck Signed-off-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck Signed-off-by: Sasha Levin --- drivers/watchdog/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/watchdog/Kconfig b/drivers/watchdog/Kconfig index 3ece1335ba84..f55328a31629 100644 --- a/drivers/watchdog/Kconfig +++ b/drivers/watchdog/Kconfig @@ -1941,6 +1941,7 @@ comment "Watchdog Pretimeout Governors" config WATCHDOG_PRETIMEOUT_GOV bool "Enable watchdog pretimeout governors" + depends on WATCHDOG_CORE help The option allows to select watchdog pretimeout governors. -- 2.20.1
