From: Krzysztof Kozlowski krzk@kernel.org Date: Thu, 30 Jan 2020 20:55:24 +0100 Subject: [PATCH] ARM: npcm: Bring back GPIOLIB support

The CONFIG_ARCH_REQUIRE_GPIOLIB is gone since commit 65053e1a7743 ("gpio: delete ARCH_[WANTS_OPTIONAL|REQUIRE]_GPIOLIB") and all platforms should explicitly select GPIOLIB to have it.
