Subject: [PATCH] pinctrl: bcm: fix kconfig dependency warning when !GPIOLIB
Git-commit: 513034d8b089b9a49dab57845aee70e830fe7334
Patch-mainline: v5.10-rc1
References: git-fixes

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.
