From 3c33b7b8267f0795d74f407e97f3eeec2acb0165 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sun, 31 Oct 2021 09:04:21 +0100 Subject: [PATCH] iio: Mark iio_device_type as const The iio_device_type struct is never modified, mark it as const. This allows it to be placed in a read-only memory section, which will protect against accidental or deliberate modification.
