Date: Sun, 21 Aug 2022 17:09:14 +0100 Message-Id: <20220821160914.2207116-1-jic23@kernel.org> X-Mailer: git-send-email 2.37.2 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-samsung-soc@vger.kernel.org From: Jonathan Cameron struct iio_chan_spec is meant to be opaque to IIO consumer drivers which should only use the interfaces in linux/iio/consumer.h. Use the provided accessor function to find get the type of the channel instead of directly reading it form the structure.
