Subject: [PATCH v2 8/8] remoteproc: Reset table_ptr on stop
Date: Fri, 5 Jan 2018 15:58:05 -0800 [thread overview]
Message-ID: <20180105235805.9948-9-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20180105235805.9948-1-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.
