From mboxrd@z Thu Jan 1 00:00:00 1970 From: arnd@arndb.de (Arnd Bergmann) Date: Mon, 2 May 2016 12:59:19 +0200 Subject: [PATCH] of: include errno.h in of_graph.h Message-ID: <1462186769-2205767-1-git-send-email-arnd@arndb.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org When CONFIG_OF is disabled, we have to include linux/errno.h before including of_graph.h, or get build errors like in the newly added sun4i drm driver: In file included from ../drivers/gpu/drm/sun4i/sun4i_drv.c:14:0: include/linux/of_graph.h: In function 'of_graph_parse_endpoint': include/linux/of_graph.h:58:10: error: 'ENOSYS' undeclared (first use in this function) A better solution is to ensure that the header can be included by itself, so let's include linux/errno.h here to fix the error we just got, and any similar future error.
