Hi Dave, After merging the drm tree, today's linux-next build (powerpc ppc64_defconfig) produced these warnings:
drivers/gpu/drm/udl/Kconfig:1:error: recursive dependency detected!
drivers/gpu/drm/udl/Kconfig:1: symbol DRM_UDL depends on USB_ARCH_HAS_HCD
drivers/usb/Kconfig:76: symbol USB_ARCH_HAS_HCD depends on USB_SUPPORT
drivers/usb/Kconfig:58: symbol USB_SUPPORT is selected by DRM_USB
drivers/gpu/drm/Kconfig:22: symbol DRM_USB is selected by DRM_UDL
warning: (PPC_PS3) selects USB_OHCI_LITTLE_ENDIAN which has unmet direct
dependencies (USB_SUPPORT && USB_OHCI_HCD)
warning: (PPC_PS3 && PPC_CELLEB) selects USB_OHCI_BIG_ENDIAN_MMIO which has

PMC_MSP || SPARC_LEON || MIPS_SEAD3))
The x86_64 allmodconfig produces these:

Maybe introduced by commit df0b34430072 ("drm/usb: select USB_SUPPORT in
Kconfig"), maybe interacting with a commit 8f057d7bca54 ("gpu/mfd/usb:
Fix USB randconfig problems") from Linus' tree (that added "depends on
USB_ARCH_HAS_HCD" to "config DRM_USB" and "config DRM_UDL").
I have left this mess for now, but it needs addressing.
