Subject: [PATCH v4 3/3] media: rkisp1: Mark subdev state pointers as const
Date: Thu, 9 May 2024 00:40:45 +0300 [thread overview]
Message-ID: <20240508214045.24716-4-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20240508214045.24716-1-laurent.pinchart+renesas@ideasonboard.com>
Several subdev state pointers are used to access the state read-only.
Mark them as const.
