Subject: [RESEND PATCH 5/5] iio: imu: lsm6dsx: Move exported symbols to the IIO_LSM6DSX namespace
Date: Sat,  4 Jun 2022 17:12:23 +0100	[thread overview]
Message-ID: <20220604161223.461847-6-jic23@kernel.org> (raw)
In-Reply-To: <20220604161223.461847-1-jic23@kernel.org>

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Avoid unnecessary pollution of the global symbol namespace by
moving library functions in to a specific namespace and import
that into the drivers that make use of the functions.
