git describe: next-20220202 git_repo: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git target_arch: arm kconfig: vexpress_defconfig toolchain: gcc-11Build log:
https://builds.tuxbuild.com/24XRim72vFXix6l6MdAJNENy6je/
Steps to reproduce:
# To install tuxmake on your system globally: # sudo pip3 install -U tuxmake # # See https://docs.tuxmake.org/ for complete documentation. # Original tuxmake command with fragments listed below.
tuxmake --runtime podman --target-arch arm --toolchain gcc-11 --kconfig vexpress_defconfig
tuxmake --runtime podman --target-arch arm --toolchain gcc-11 --kconfig https://builds.tuxbuild.com/24XRim72vFXix6l6MdAJNENy6je/config
You'll now need
CONFIG_DRM_DP_HELPER=yin your config.
That should never be the solution for linker errors such as this one.
If CONFIG_DRM_PANEL_EDP relies on something provided by CONFIG_DRM_DP_HELPER, it should select it or depend on it in Kconfig.
Of course, we'll provide a patch for the Kconfig files.
There was discussion about this last November but I guess nothing came of it?

In there Arnd provided a proposed patch. If everyone likes that and it fixes things then we can apply it...
