It choked on msm/mdp/mdp5/mdp5_plane.c like so: "BAD:!!!!! enum drm_plane_type type;" No idea how to deal with that, so I just fixed that up by hand. Also it thinks '...' is part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder in its place and got rid of it with sed afterwards. I didn't convert drm_plane_init() since passing the varargs through would mean either cpp macros or va_list, and I figured we don't care about these legacy functions enough to warrant the extra pain. @@ typedef uint32_t; identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ) { ... } @@ identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ); @@ expression E1, E2, E3, E4, E5, E6, E7; @@ drm_universal_plane_init(E1, E2, E3, E4, E5, E6, E7 + ,NULL ) v2: Split crtc and plane changes apart Pass NUL for no-name instead of "" Leave drm_plane_init() alone v3: Add ', or NULL...' to @name kernel doc (Jani) Annotate the function with __printf() attribute (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1449670795-2853-1-git-send-email-ville.syrjala@linux.intel.com
