Hi Joachim, there are two of your commits [1, 2] in today's linux-next (i.e., next-20150506). Both of them add Kconfig options that depend on ARCH_LPC18XX, which is not defined in Kconfig, see: + depends on OF && (ARCH_LPC18XX || COMPILE_TEST) Is there a patch queued somewhere to add ARCH_LPC18XX ? I detected this issue with ./scripts/checkkconfigsymbols.py by diffing yesterday's and todays' linux-next trees. Kind regards, Valentin [1] 13a43fd9e905 ("gpio: add lpc18xx gpio driver") [2] 3aba09daf3d4 ("pinctrl: add lpc18xx pinctrl driver") -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
