    Subject[PATCH 4.14 067/124] watchdog/core: Add missing prototypes for weak functions
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Mathieu Malaterre <malat@debian.org>

    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")
