The drm_crtc_mask() function used in <drm/drm_encoder.h> is a static inline defined in <drm/drm_crtc.h>. If the first header is included in a compilation unit without the second one, the following compilation warning will be issued. In file included from <linux>/drivers/gpu/drm/drm_bridge.c:29:0: <linux>/include/drm/drm_encoder.h:192:95: warning: ‘drm_crtc_mask’ used but never defined static inline uint32_t drm_crtc_mask(const struct drm_crtc *crtc); Fix this by including the header defining the function instead of using a forward declaration.
