Subject: [PATCH] iio: imx8qxp-adc: Fix the error - defined but not used for runtime pm API
Date:   Wed, 13 Oct 2021 09:46:58 +0800
Message-ID: <20211013014658.2798-1-caihuoqing@baidu.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Add the prefix '__maybe_unused' to imx8qxp_adc_runtime_suspend/resume()
to avoid the compiler complain without setting CONFIG_SUSPEND,
CONFIG_HIBERNATION and CONFIG_PM.
