The same config file builds successfully on linux-next of Mar. 27. I looked more at linux-next of Mar. 26 and found one problem: in drivers/gpu/drm/Kconfig, there is a "select USB" that should be protected by "depends on USB_ARCH_HAS_HCD". I did that and then kconfig complained about unmet dependencies in drivers/gpu/drm/udl/Kconfig, so I added the same "depends on" there. That led into an awful mess: drivers/video/Kconfig:36:error: recursive dependency detected! drivers/video/Kconfig:36: symbol FB is selected by DRM_KMS_HELPER drivers/gpu/drm/Kconfig:26: symbol DRM_KMS_HELPER is selected by DRM_UDL drivers/gpu/drm/udl/Kconfig:1: symbol DRM_UDL depends on USB_ARCH_HAS_HCD drivers/usb/Kconfig:78: symbol USB_ARCH_HAS_HCD depends on USB_ARCH_HAS_OHCI drivers/usb/Kconfig:24: symbol USB_ARCH_HAS_OHCI depends on I2C drivers/i2c/Kconfig:5: symbol I2C is selected by FB_DDC drivers/video/Kconfig:86: symbol FB_DDC is selected by FB_CYBER2000_DDC drivers/video/Kconfig:385: symbol FB_CYBER2000_DDC depends on FB_CYBER2000 drivers/video/Kconfig:373: symbol FB_CYBER2000 depends on FB and I don't know what to do with this. Anyway, I do think that the problem is in drivers/gpu/drm/Kconfig and drivers/gpu/drm/udl/Kconfig. -- ~Randy -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
