Subject: [PATCH 03/10] thermal: tegra: Constify SoC-specific data
Date: Fri, 14 Apr 2023 14:57:14 +0200	[thread overview]
Message-ID: <20230414125721.1043589-4-thierry.reding@gmail.com> (raw)
In-Reply-To: <20230414125721.1043589-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

The SoC-specific parameter structure is read-only data, so consistently
use const to mark it as such.
