Subject: [PATCH 8/8] remoteproc: k3-dsp: Use devm_rproc_add() helper
Date: Tue, 23 Jan 2024 12:49:13 -0600	[thread overview]
Message-ID: <20240123184913.725435-8-afd@ti.com> (raw)
In-Reply-To: <20240123184913.725435-1-afd@ti.com>

Use device lifecycle managed devm_rproc_add() helper function. This helps
prevent mistakes like deleting out of order in cleanup functions and
forgetting to delete on all error paths.
