If this is a question about "kconfig itself", you should probably have included the correct ML and Maintainer: KCONFIG M: Michal Marek <mmarek@xxxxxxx> L: linux-kbuild@xxxxxxxxxxxxxxx S: Odd Fixes F: Documentation/kbuild/kconfig-language.txt F: scripts/kconfig/ There are also quite a few interested parties on LKML who might be inclined to submit a fix for you. -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
