From 952e8faec53ec1de045f44f48a82e5069d2f17b4 Mon Sep 17 00:00:00 2001 From: Baoyou Xie Date: Thu, 8 Sep 2016 19:29:24 +0800 Subject: [PATCH] drm/tilcdc: mark symbols static where possible We get 3 warnings when building kernel with W=1: drivers/gpu/drm/tilcdc/tilcdc_slave_compat.c:142:29: warning: no previous prototype for 'tilcdc_get_overlay' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_slave_compat.c:198:13: warning: no previous prototype for 'tilcdc_convert_slave_node' [-Wmissing-prototypes] drivers/gpu/drm/tilcdc/tilcdc_slave_compat.c:264:12: warning: no previous prototype for 'tilcdc_slave_compat_init' [-Wmissing-prototypes] In fact, these functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks these functions with 'static'.
