Hi, I am getting build failures in v4l2-fwnode.c. I'm sending this because the daily build logs are not showing any errors for this kernel (version below). I've tried flushing the git checkout and rerunning but I still get the failures. I can send a fuller log off-list if you like. /home/me/git/clones/media_build/v4l/v4l2-fwnode.c: In function 'v4l2_fwnode_endpoint_parse_csi2_bus': /home/me/git/clones/media_build/v4l/v4l2-fwnode.c:166:9: error: implicit declaration of function 'fwnode_property_count_u32' [-Werror=implicit-function-declaration] rval = fwnode_property_count_u32(fwnode, "data-lanes"); ^ /home/me/git/clones/media_build/v4l/v4l2-fwnode.c: In function 'v4l2_fwnode_endpoint_alloc_parse': /home/me/git/clones/media_build/v4l/v4l2-fwnode.c:527:9: error: implicit declaration of function 'fwnode_property_count_u64' [-Werror=implicit-function-declaration] rval = fwnode_property_count_u64(fwnode, "link-frequencies"); ^ /home/me/git/clones/media_build/v4l/v4l2-fwnode.c: At top level: cc1: warning: unrecognized command line option '-Wno-format-truncation' cc1: some warnings being treated as errors scripts/Makefile.build:339: recipe for target '/home/me/git/clones/media_build/v4l/v4l2-fwnode.o' failed make[3]: *** [/home/me/git/clones/media_build/v4l/v4l2-fwnode.o] Error 1 Makefile:1552: recipe for target '_module_/home/me/git/clones/media_build/v4l' failed make[2]: *** [_module_/home/me/git/clones/media_build/v4l] Error 2 make[2]: Leaving directory '/usr/src/linux-headers-4.15.0-47-generic' Makefile:51: recipe for target 'default' failed make[1]: *** [default] Error 2 make[1]: Leaving directory '/home/me/git/clones/media_build/v4l' Makefile:26: recipe for target 'all' failed make: *** [all] Error 2 build failed at ./build line 526 $ cat /proc/version_signature Ubuntu 4.15.0-55.60~16.04.2-generic 4.15.18 Also seen on Ubuntu 4.15.0-47.50~16.04.1-generic 4.15.18 $ git --no-pager log -1 commit 5158c420e7a0929fa58c56ac437e274e8b1c37d1 Author: Hans Verkuil <hverkuil-cisco@xxxxxxxxx> Date: Fri Jul 26 09:26:30 2019 +0200 Remove const from fwnode_property_count_u32/u64 Signed-off-by: Hans Verkuil <hverkuil-cisco@xxxxxxxxx> $ cd media; git --no-pager log -1 commit d2b4387f3bdf016e266d23cf657465f557721488 Author: Eddie James <eajames@xxxxxxxxxxxxx> Date: Tue Dec 11 11:57:01 2018 -0500 media: platform: Add Aspeed Video Engine driver The Video Engine (VE) embedded in the Aspeed AST2400 and AST2500 SOCs can capture and compress video data from digital or analog sources. With the Aspeed chip acting a service processor, the Video Engine can capture the host processor graphics output. Add a V4L2 driver to capture video data and compress it to JPEG images. Make the video frames available through the V4L2 streaming interface.
