From 4cd6764495f2b6c2d3dc4fdd339f78764f7995d5 Mon Sep 17 00:00:00 2001 From: Radu Rendec Date: Mon, 19 Feb 2018 14:38:51 +0000 Subject: [PATCH] watchdog: xen_wdt: fix potential build failure xen_wdt uses watchdog core functions (from watchdog_core.c) and, when compiled without CONFIG_WATCHDOG_CORE being set, it produces the following build error: ERROR: "devm_watchdog_register_device" [drivers/watchdog/xen_wdt.ko] undefined! ERROR: "watchdog_init_timeout" [drivers/watchdog/xen_wdt.ko] undefined! Fix this by selecting CONFIG_WATCHDOG_CORE when CONFIG_XEN_WDT is set.
