Subject: [PATCH 8/8] remoteproc: Reset table_ptr on stop
Date: Wed, 13 Dec 2017 14:41:11 -0800 [thread overview]
Message-ID: <20171213224111.17864-9-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20171213224111.17864-1-bjorn.andersson@linaro.org>
The installed resource table is no longer accessible after stopping the
remote, so update table_ptr to point to the local copy.
