Subject[PATCH 4.18 099/171] watchdog/core: Add missing prototypes for weak functions
4.18-stable review patch.  If anyone has any objections, please let me know.


From: Mathieu Malaterre <>

commit 81bd415c91eb966118d773dddf254aebf3022411 upstream.

The split out of the hard lockup detector exposed two new weak functions,
but no prototypes for them, which triggers the build warning:

kernel/watchdog.c:109:12: warning: no previous prototype for ‘watchdog_nmi_enable’ [-Wmissing-prototypes]
kernel/watchdog.c:115:13: warning: no previous prototype for ‘watchdog_nmi_disable’ [-Wmissing-prototypes]

Add the prototypes.

Fixes: 73ce0511c436 ("kernel/watchdog.c: move hardlockup detector to separate file")
