Subject: [PATCH] iio: adc: ad7768-1: Select GPIOLIB
Date: Sun, 11 Jan 2026 16:55:28 +0000 [thread overview]
Message-ID: <20260111165528.284067-1-jic23@kernel.org> (raw)
From: Jonathan Cameron <Jonathan.Cameron@huawei.com>
This driver provides a gpio chip a some related functions are not
stubbed if GPIOLIB is not built.
