Subject: [PATCH 2/8] remoteproc: k3-dsp: Add devm action to release reserved memory
Date: Tue, 23 Jan 2024 12:49:07 -0600 [thread overview]
Message-ID: <20240123184913.725435-2-afd@ti.com> (raw)
In-Reply-To: <20240123184913.725435-1-afd@ti.com>
Use a device lifecycle managed action to release reserved memory. This
helps prevent mistakes like releasing out of order in cleanup functions
and forgetting to release on error paths.
