Can you please fix it up?
I can repro this with:
make -j 16 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- \ KCONFIG_ALLCONFIG=arch/arm64/configs/defconfig allmodconfig kernel modules
This results in:
CONFIG_USB_XHCI_PLATFORM=y CONFIG_USB_ONBOARD_HUB=m
The following Kconfig dependency was supposed to prevent this scenario:
config USB_XHCI_PLATFORM depends on USB_ONBOARD_HUB || !USB_ONBOARD_HUB
But apparently this isn't the case.
With the above allmodconfig command the following warning is emitted:
WARNING: unmet direct dependencies detected for USB_XHCI_PLATFORM Depends on [m]: USB_SUPPORT [=y] && USB [=y] && USB_XHCI_HCD [=y] && (USB_ONBOARD_HUB [=m] || !USB_ONBOARD_HUB [=m])
I read through kconfig-language.rst multiple times, but it's still not clear to me how to specify this dependency properly.
Masahiro/Greg, do you have any pointers?
