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/vc4/vc4_dpi.c:309:2: error: implicit declaration of function 'drm_simple_encoder_init' [-Werror,-Wimplicit-function-declaration] drm_simple_encoder_init(drm, dpi->encoder, DRM_MODE_ENCODER_DPI); ^ drivers/gpu//drm/vc4/vc4_dpi.c:309:2: 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/vc4/vc4_dsi.c:1610:2: error: implicit declaration of function 'drm_simple_encoder_init' [-Werror,-Wimplicit-function-declaration] drm_simple_encoder_init(drm, dsi->encoder, DRM_MODE_ENCODER_DSI); ^ drivers/gpu//drm/vc4/vc4_dsi.c:1610:2: 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/vc4/vc4_hdmi.c:1389:2: error: implicit declaration of function 'drm_simple_encoder_init' [-Werror,-Wimplicit-function-declaration] drm_simple_encoder_init(drm, hdmi->encoder, DRM_MODE_ENCODER_TMDS); ^ drivers/gpu//drm/vc4/vc4_hdmi.c:1389:2: 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/vc4/vc4_vec.c:566:2: error: implicit declaration of function 'drm_simple_encoder_init' [-Werror,-Wimplicit-function-declaration] drm_simple_encoder_init(drm, vec->encoder, DRM_MODE_ENCODER_TVDAC); ^ drivers/gpu//drm/vc4/vc4_vec.c:566:2: 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/vc4/vc4_dpi.c 254 255 static int vc4_dpi_bind(struct device *dev, struct device *master, void *data) 256 { 257 struct platform_device *pdev = to_platform_device(dev); 258 struct drm_device *drm = dev_get_drvdata(master); 259 struct vc4_dev *vc4 = to_vc4_dev(drm); 260 struct vc4_dpi *dpi; 261 struct vc4_dpi_encoder *vc4_dpi_encoder; 262 int ret; 263 264 dpi = devm_kzalloc(dev, sizeof(*dpi), GFP_KERNEL); 265 if (!dpi) 266 return -ENOMEM; 267 268 vc4_dpi_encoder = devm_kzalloc(dev, sizeof(*vc4_dpi_encoder), 269 GFP_KERNEL); 270 if (!vc4_dpi_encoder) 271 return -ENOMEM; 272 vc4_dpi_encoder->base.type = VC4_ENCODER_TYPE_DPI; 273 vc4_dpi_encoder->dpi = dpi; 274 dpi->encoder = &vc4_dpi_encoder->base.base; 275 276 dpi->pdev = pdev; 277 dpi->regs = vc4_ioremap_regs(pdev, 0); 278 if (IS_ERR(dpi->regs)) 279 return PTR_ERR(dpi->regs); 280 dpi->regset.base = dpi->regs; 281 dpi->regset.regs = dpi_regs; 282 dpi->regset.nregs = ARRAY_SIZE(dpi_regs); 283 284 if (DPI_READ(DPI_ID) != DPI_ID_VALUE) { 285 dev_err(dev, "Port returned 0x%08x for ID instead of 0x%08x\n", 286 DPI_READ(DPI_ID), DPI_ID_VALUE); 287 return -ENODEV; 288 } 289 290 dpi->core_clock = devm_clk_get(dev, "core"); 291 if (IS_ERR(dpi->core_clock)) { 292 ret = PTR_ERR(dpi->core_clock); 293 if (ret != -EPROBE_DEFER) 294 DRM_ERROR("Failed to get core clock: %d\n", ret); 295 return ret; 296 } 297 dpi->pixel_clock = devm_clk_get(dev, "pixel"); 298 if (IS_ERR(dpi->pixel_clock)) { 299 ret = PTR_ERR(dpi->pixel_clock); 300 if (ret != -EPROBE_DEFER) 301 DRM_ERROR("Failed to get pixel clock: %d\n", ret); 302 return ret; 303 } 304 305 ret = clk_prepare_enable(dpi->core_clock); 306 if (ret) 307 DRM_ERROR("Failed to turn on core clock: %d\n", ret); 308 > 309 drm_simple_encoder_init(drm, dpi->encoder, DRM_MODE_ENCODER_DPI); 310 drm_encoder_helper_add(dpi->encoder, &vc4_dpi_encoder_helper_funcs); 311 312 ret = vc4_dpi_init_bridge(dpi); 313 if (ret) 314 goto err_destroy_encoder; 315 316 dev_set_drvdata(dev, dpi); 317 318 vc4->dpi = dpi; 319 320 vc4_debugfs_add_regset32(drm, "dpi_regs", &dpi->regset); 321 322 return 0; 323 324 err_destroy_encoder: 325 drm_encoder_cleanup(dpi->encoder); 326 clk_disable_unprepare(dpi->core_clock); 327 return ret; 328 } 329 --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@xxxxxxxxxxxx
