Hi Sakari, It has uploaded fixed V2 patch to the server. * [PATCH v2] media: hi847: Add support for Hi-847 sensor https://github.com/0day-ci/linux/commits/Shawnx-Tu/media-hi847-Add-suppor... But I still see the lkp build error message and use previous V1 patch to build. Could you help to check? If needs to fix the driver, I'll upload new one. ret = v4l2_async_register_subdev_sensor_common(&hi847->sd); ^ Thanks, Shawn -----Original Message----- From: lkp <lkp(a)intel.com&gt; Sent: Friday, January 14, 2022 5:14 PM To: Tu, ShawnX <shawnx.tu(a)intel.com&gt; Cc: llvm(a)lists.linux.dev; kbuild-all(a)lists.01.org; linux-kernel(a)vger.kernel.org; Sakari Ailus <sakari.ailus(a)linux.intel.com&gt; Subject: [sailus-media-tree:master 15/16] drivers/media/i2c/hi847.c:2700:35: error: incompatible pointer types passing 'struct v4l2_subdev_pad_config *' to parameter of type 'struct v4l2_subdev_state *' tree: git://linuxtv.org/sailus/media_tree.git master head: 232068c0bf39d2e34585450343c1439a89aad66b commit: 009f8036169f02f87f7fd5e3152f6dcd03986a81 [15/16] media: hi847: Add support for Hi-847 sensor config: i386-allyesconfig (https://download.01.org/0day-ci/archive/20220114/202201141739.Q7kFIE7g-lk...) compiler: clang version 14.0.0 (https://github.com/llvm/llvm-project 244dd2913a43a200f5a6544d424cdc37b771028b) reproduce (this is a W=1 build): wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross git remote add sailus-media-tree git://linuxtv.org/sailus/media_tree.git git fetch --no-tags sailus-media-tree master git checkout 009f8036169f02f87f7fd5e3152f6dcd03986a81 # save the config file to linux build tree mkdir build_dir COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross W=1 O=build_dir ARCH=i386 SHELL=/bin/bash If you fix the issue, kindly add following tag as appropriate Reported-by: kernel test robot <lkp(a)intel.com&gt; All errors (new ones prefixed by >>): *v4l2_subdev_get_try_format(sd, cfg, fmt->pad) = fmt->format; ^~~ include/media/v4l2-subdev.h:982:33: note: passing argument to parameter 'state' here struct v4l2_subdev_state *state, ^ drivers/media/i2c/hi847.c:2734:57: error: incompatible pointer types passing 'struct v4l2_subdev_pad_config *' to parameter of type 'struct v4l2_subdev_state *' [-Werror,-Wincompatible-pointer-types] fmt->format = *v4l2_subdev_get_try_format(&hi847->sd, cfg, ^~~ include/media/v4l2-subdev.h:982:33: note: passing argument to parameter 'state' here struct v4l2_subdev_state *state, ^ v4l2_subdev_get_try_format(sd, fh->pad, 0)); ~~ ^ .set_fmt = hi847_set_format, ^~~~~~~~~~~~~~~~ drivers/media/i2c/hi847.c:2792:13: error: incompatible function pointer types initializing 'int (*)(struct v4l2_subdev *, struct v4l2_subdev_state *, struct v4l2_subdev_format *)' with an expression of type 'int (struct v4l2_subdev *, struct v4l2_subdev_pad_config *, struct v4l2_subdev_format *)' [-Werror,-Wincompatible-function-pointer-types] .get_fmt = hi847_get_format, ^~~~~~~~~~~~~~~~ .enum_mbus_code = hi847_enum_mbus_code, ^~~~~~~~~~~~~~~~~~~~ .enum_frame_size = hi847_enum_frame_size, ^~~~~~~~~~~~~~~~~~~~~ ret = v4l2_async_register_subdev_sensor_common(&hi847->sd); ^ drivers/media/i2c/hi847.c:2954:8: note: did you mean 'v4l2_async_register_subdev_sensor'?
