Subject: [PATCH] drm/etnaviv: constify static struct cooling_ops
Date:   Sun, 28 Nov 2021 21:19:16 +0100
Message-Id: <20211128201916.10230-1-rikard.falkeborn@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The only usage of cooling_ops is to pass its address to
thermal_of_cooling_device_register(), which takes a pointer to const
struct thermal_cooling_device_ops as input. Make it const to allow the
compiler to put it in read-only memory.
