Hi Matthew, After merging the drivers-x86 tree, today's linux-next build (powerpc ppc64_defconfig and x86_64 allmodconfig) produced this warning: drivers/video/backlight/Kconfig:117:error: recursive dependency detected! drivers/video/backlight/Kconfig:117: symbol BACKLIGHT_CLASS_DEVICE is selected by ACPI_TOSHIBA drivers/platform/x86/Kconfig:490: symbol ACPI_TOSHIBA depends on LEDS_CLASS drivers/leds/Kconfig:12: symbol LEDS_CLASS is selected by BACKLIGHT_ADP8860 drivers/video/backlight/Kconfig:285: symbol BACKLIGHT_ADP8860 depends on BACKLIGHT_CLASS_DEVICE Introduced by commit af7ad65329f59cdfdd564ec26148160ed42a8b70 ("toshiba-acpi - switch to using sparse keymap") -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
