Subject: [PATCH v2 6/6] remoteproc: imx_rproc: Clean up after ops introduction
Date: Wed, 10 Sep 2025 15:11:50 +0800	[thread overview]
Message-ID: <20250910-imx-rproc-cleanup-v2-6-10386685b8a9@nxp.com> (raw)
In-Reply-To: <20250910-imx-rproc-cleanup-v2-0-10386685b8a9@nxp.com>

With the switch-case in imx_rproc_{start,stop}{} removed, simplify
the code logic by removing 'goto'. The last switch-case in
imx_rproc_detect_mode() are no longer needed and can be removed.

This cleanup improves code readability and aligns with the new ops-based
design.

No functional changes.
