Hi Thomas, I love your patch! Yet something to improve: [auto build test ERROR on next-20200305] [cannot apply to rockchip/for-next shawnguo/for-next sunxi/sunxi/for-next tegra/for-next linus/master v5.6-rc4 v5.6-rc3 v5.6-rc2 v5.6-rc4] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Thomas-Zimmermann/drm-Convert-drivers-to-drm_simple_encoder_init/20200306-045931 base: 47466dcf84ee66a973ea7d2fca7e582fe9328932 config: arm64-defconfig (attached as .config) compiler: clang version 11.0.0 (git://gitmirror/llvm_project a0cd413426479abb207381bdbab862f3dfb3ce7d) reproduce: # FIXME the reproduce steps for clang is not ready yet If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp@xxxxxxxxx> All errors (new ones prefixed by >>): >> drivers/gpu/drm/rockchip/analogix_dp-rockchip.c:309:8: error: implicit declaration of function 'drm_simple_encoder_init' [-Werror,-Wimplicit-function-declaration] ret = drm_simple_encoder_init(drm_dev, encoder, ^ drivers/gpu/drm/rockchip/analogix_dp-rockchip.c:309:8: note: did you mean 'drm_encoder_init'? include/drm/drm_encoder.h:189:5: note: 'drm_encoder_init' declared here int drm_encoder_init(struct drm_device *dev, ^ 1 error generated. -- >> drivers/gpu/drm/rockchip/cdn-dp-core.c:1030:8: error: implicit declaration of function 'drm_simple_encoder_init' [-Werror,-Wimplicit-function-declaration] ret = drm_simple_encoder_init(drm_dev, encoder, ^ drivers/gpu/drm/rockchip/cdn-dp-core.c:1030:8: note: did you mean 'drm_encoder_init'? include/drm/drm_encoder.h:189:5: note: 'drm_encoder_init' declared here int drm_encoder_init(struct drm_device *dev, ^ 1 error generated. -- >> drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c:546:2: error: implicit declaration of function 'drm_simple_encoder_init' [-Werror,-Wimplicit-function-declaration] drm_simple_encoder_init(drm, encoder, DRM_MODE_ENCODER_TMDS); ^ drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c:546:2: note: did you mean 'drm_encoder_init'? include/drm/drm_encoder.h:189:5: note: 'drm_encoder_init' declared here int drm_encoder_init(struct drm_device *dev, ^ 1 error generated. -- >> drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c:802:8: error: implicit declaration of function 'drm_simple_encoder_init' [-Werror,-Wimplicit-function-declaration] ret = drm_simple_encoder_init(drm_dev, encoder, DRM_MODE_ENCODER_DSI); ^ drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c:802:8: note: did you mean 'drm_encoder_init'? include/drm/drm_encoder.h:189:5: note: 'drm_encoder_init' declared here int drm_encoder_init(struct drm_device *dev, ^ 1 error generated. -- >> drivers/gpu/drm/rockchip/inno_hdmi.c:617:2: error: implicit declaration of function 'drm_simple_encoder_init' [-Werror,-Wimplicit-function-declaration] drm_simple_encoder_init(drm, encoder, DRM_MODE_ENCODER_TMDS); ^ drivers/gpu/drm/rockchip/inno_hdmi.c:617:2: note: did you mean 'drm_encoder_init'? include/drm/drm_encoder.h:189:5: note: 'drm_encoder_init' declared here int drm_encoder_init(struct drm_device *dev, ^ 1 error generated. vim +/drm_simple_encoder_init +309 drivers/gpu/drm/rockchip/analogix_dp-rockchip.c 297 298 static int rockchip_dp_drm_create_encoder(struct rockchip_dp_device *dp) 299 { 300 struct drm_encoder *encoder = &dp->encoder; 301 struct drm_device *drm_dev = dp->drm_dev; 302 struct device *dev = dp->dev; 303 int ret; 304 305 encoder->possible_crtcs = drm_of_find_possible_crtcs(drm_dev, 306 dev->of_node); 307 DRM_DEBUG_KMS("possible_crtcs = 0x%x\n", encoder->possible_crtcs); 308 > 309 ret = drm_simple_encoder_init(drm_dev, encoder, 310 DRM_MODE_ENCODER_TMDS); 311 if (ret) { 312 DRM_ERROR("failed to initialize encoder with drm\n"); 313 return ret; 314 } 315 316 drm_encoder_helper_add(encoder, &rockchip_dp_encoder_helper_funcs); 317 318 return 0; 319 } 320 --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@xxxxxxxxxxxx
