Subject: [PATCH 2/3] coresight tmc etr: Fix uninitialised variable
Date: Thu, 19 Apr 2018 11:39:45 -0600 [thread overview]
Message-ID: <1524159586-4841-3-git-send-email-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <1524159586-4841-1-git-send-email-mathieu.poirier@linaro.org>
Variable 'paddr' can't be used if uninitialised but is nonetheless
confusing to some static checker. As such simply initialise it to zero.
