Hi, I updated my config and set CONFIG_WDAT_WDT=y, got this: drivers/built-in.o: In function `wdat_wdt_probe': /home/vegard/linux/drivers/watchdog/wdat_wdt.c:444: undefined reference to `devm_watchdog_register_device' Makefile:962: recipe for target 'vmlinux' failed make: *** [vmlinux] Error 1 Looks like it's missing a select for WATCHDOG_CORE in the Kconfig?
