From b0b39af1bc04b173575b8e2d6b717abc8daad32a Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Thu, 20 Dec 2018 00:03:59 +0100 Subject: [PATCH] LOGPFSM*: guard against fi == NULL The LOGPFSM macros are in such wide use that they should guard against a NULL fi pointer. In case of NULL, default to subsys = DLGLOBAL, loglevel = LOGL_ERROR and state = "fi=NULL".
