Subject: [PATCH 3/5] coresight: Don't initialize variables unnecessarily
Date: Sun, 26 Apr 2020 11:58:03 -0700	[thread overview]
Message-ID: <20200426185805.14923-4-swboyd@chromium.org> (raw)
In-Reply-To: <20200426185805.14923-1-swboyd@chromium.org>

These variables are assigned again before they're used. Leave them
unassigned at first so that the compiler can detect problems in the
future with use before initialization.
