Subject: [PATCH 6/9] remoteproc: qcom_q6v5_wcss: Use devm_rproc_alloc() helper
Date: Tue, 23 Jan 2024 12:46:29 -0600	[thread overview]
Message-ID: <20240123184632.725054-6-afd@ti.com> (raw)
In-Reply-To: <20240123184632.725054-1-afd@ti.com>

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