lkp robot told me: >> drivers/gpu/drm/drm_ioc32.c:989:2: error: call to undeclared function '_dynamic_func_call_cls'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] DRM_DEBUG("comm=\"%s\", pid=%d, dev=0x%lx, auth=%d, %s\n", Since that macro is defined in drm_print.h, include <dynamic_debug.h> there too, so that any uses have the definitions of all the macros in the callchain. This is done as a separate patch mostly to see how lkp sorts it; I'll probably squash it with HEAD~1 Signed-off-by: Jim Cromie <jim.cromie@xxxxxxxxx> --- include/drm/drm_print.h | 1 + 1 file changed, 1 insertion(+) diff --git a/include/drm/drm_print.h b/include/drm/drm_print.h index 2d2cef76b5c1..f8bb3e7158c6 100644 --- a/include/drm/drm_print.h +++ b/include/drm/drm_print.h @@ -31,6 +31,7 @@ #include <linux/seq_file.h> #include <linux/device.h> #include <linux/debugfs.h> +#include <linux/dynamic_debug.h> #include <drm/drm.h> -- 2.36.1
