Subject: [PATCH v4 08/13] iio: inkern: Use max_array() to get the maximum value from an array
Date: Wed, 14 Jun 2023 09:48:59 +0200 [thread overview]
Message-ID: <20230614074904.29085-9-herve.codina@bootlin.com> (raw)
In-Reply-To: <20230614074904.29085-1-herve.codina@bootlin.com>
Use max_array() to get the maximum value from an array instead of a
custom local loop.
