Subject: [PATCH 2/2] iio: light: cm3232: make struct cm3232_als_info const
Date: Sat, 28 Jun 2025 12:52:31 -0500	[thread overview]
Message-ID: <20250628-iio-const-data-20-v1-2-2bf90b03f9f1@baylibre.com> (raw)
In-Reply-To: <20250628-iio-const-data-20-v1-0-2bf90b03f9f1@baylibre.com>

Add const qualifier to struct cm3232_als_info. This is read-only data so
it can be made const.
