Subject: [dpdk-dev] [PATCH v3 1/3] cfgfile: remove unnecessary initialization
Date: Thu, 18 Jul 2019 10:18:10 -0700	[thread overview]
Message-ID: <20190718171812.3209-2-stephen@networkplumber.org> (raw)
In-Reply-To: <20190718171812.3209-1-stephen@networkplumber.org>

No need to initialize variable if it is immediately overwritten.
It is better style not do unnecessary initialization with modern
tools since it lets compiler and other static checkers detect
uninitialized data.
