Subject: [PATCH 6/8] iio: humidity: hts221: Move symbol exports into IIO_HTS221 namespace
Date: Sun, 20 Feb 2022 18:15:20 +0000	[thread overview]
Message-ID: <20220220181522.541718-7-jic23@kernel.org> (raw)
In-Reply-To: <20220220181522.541718-1-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.
