Hi Linus,

After merging the gpio tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/gpio/Kconfig:13:error: recursive dependency detected!
drivers/gpio/Kconfig:13: symbol GPIOLIB is selected by STX104
drivers/iio/adc/Kconfig:699: symbol STX104 depends on ISA_BUS_API
arch/Kconfig:821: symbol ISA_BUS_API is selected by GPIO_WINBOND
drivers/gpio/Kconfig:701: symbol GPIO_WINBOND depends on GPIOLIB
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"

Presumably introduced by commit

a0d65009411c ("gpio: winbond: Add driver")
