Subject: [PATCH v10 3/7] remoteproc: core: Refactor resource table cleanup into rproc_release_fw
Date: Mon, 7 Oct 2024 15:16:16 +0200	[thread overview]
Message-ID: <20241007131620.2090104-4-arnaud.pouliquen@foss.st.com> (raw)
In-Reply-To: <20241007131620.2090104-1-arnaud.pouliquen@foss.st.com>

This patch centralizing the cleanup of the resource table into a new
helper function rproc_release_fw().

More than just factorizing the code into a common function, it is the
first step to integrate the release of the firmware image loaded by the
OP-TEE remoteproc framework.

Suggested-by: Mathieu Poirier <mathieu.poirier@linaro.org>
