Subject: [PATCH 3/8] remoteproc: k3-dsp: Use devm_kcalloc() helper
Date: Tue, 23 Jan 2024 12:49:08 -0600	[thread overview]
Message-ID: <20240123184913.725435-3-afd@ti.com> (raw)
In-Reply-To: <20240123184913.725435-1-afd@ti.com>

Use a device lifecycle managed action to free memory. This helps prevent
mistakes like freeing out of order in cleanup functions and forgetting to
free on error paths.
