If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 9140ca8f4d4d945316e2e432950d00c23140d8c5 Author: Necip Fazil Yildiran <fazilyildiran@xxxxxxxxx> Date: Mon Sep 14 17:40:26 2020 +0300 pinctrl: bcm: fix kconfig dependency warning when !GPIOLIB [ Upstream commit 513034d8b089b9a49dab57845aee70e830fe7334 ] When PINCTRL_BCM2835 is enabled and GPIOLIB is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for GPIOLIB_IRQCHIP Depends on [n]: GPIOLIB [=n] Selected by [y]: - PINCTRL_BCM2835 [=y] && PINCTRL [=y] && OF [=y] && (ARCH_BCM2835 [=n] || ARCH_BRCMSTB [=n] || COMPILE_TEST [=y]) The reason is that PINCTRL_BCM2835 selects GPIOLIB_IRQCHIP without depending on or selecting GPIOLIB while GPIOLIB_IRQCHIP is subordinate to GPIOLIB. Honor the kconfig menu hierarchy to remove kconfig dependency warnings.
