Include the drm_plane_helper.h header file to fix the following sparse warnings: CHECK drivers/gpu/drm/drm_plane_helper.c drivers/gpu/drm/drm_plane_helper.c:102:5: warning: symbol 'drm_primary_helper_update' was not declared. Should it be static? drivers/gpu/drm/drm_plane_helper.c:219:5: warning: symbol 'drm_primary_helper_disable' was not declared. Should it be static? drivers/gpu/drm/drm_plane_helper.c:233:6: warning: symbol 'drm_primary_helper_destroy' was not declared. Should it be static? drivers/gpu/drm/drm_plane_helper.c:241:30: warning: symbol 'drm_primary_helper_funcs' was not declared. Should it be static? drivers/gpu/drm/drm_plane_helper.c:259:18: warning: symbol 'drm_primary_helper_create_plane' was not declared. Should it be static? Doing that makes gcc complain as follows: CC drivers/gpu/drm/drm_plane_helper.o drivers/gpu/drm/drm_plane_helper.c:260:19: error: conflicting types for 'drm_primary_helper_create_plane' struct drm_plane *drm_primary_helper_create_plane(struct drm_device *dev, ^ In file included from drivers/gpu/drm/drm_plane_helper.c:29:0: include/drm/drm_plane_helper.h:42:19: note: previous declaration of 'drm_primary_helper_create_plane' was here struct drm_plane *drm_primary_helper_create_plane(struct drm_device *dev, ^ drivers/gpu/drm/drm_plane_helper.c: In function 'drm_primary_helper_create_plane': drivers/gpu/drm/drm_plane_helper.c:274:11: warning: assignment discards 'const' qualifier from pointer target type formats = safe_modeset_formats; ^ In file included from include/linux/linkage.h:6:0, from include/linux/kernel.h:6, from include/drm/drmP.h:45, from drivers/gpu/drm/drm_plane_helper.c:27: drivers/gpu/drm/drm_plane_helper.c: At top level: drivers/gpu/drm/drm_plane_helper.c:289:15: error: conflicting types for 'drm_primary_helper_create_plane' EXPORT_SYMBOL(drm_primary_helper_create_plane); ^ include/linux/export.h:57:21: note: in definition of macro '__EXPORT_SYMBOL' extern typeof(sym) sym; \ ^ drivers/gpu/drm/drm_plane_helper.c:289:1: note: in expansion of macro 'EXPORT_SYMBOL' EXPORT_SYMBOL(drm_primary_helper_create_plane); ^ In file included from drivers/gpu/drm/drm_plane_helper.c:29:0: include/drm/drm_plane_helper.h:42:19: note: previous declaration of 'drm_primary_helper_create_plane' was here struct drm_plane *drm_primary_helper_create_plane(struct drm_device *dev, ^ Which can easily be fixed by making the signatures of the implementation and the prototype match.
