Subject: [libnftnl PATCH 3/6] src/object: Avoid returning garbage in nftnl_obj_do_parse()
Date: Thu, 14 Dec 2017 20:40:22 +0100	[thread overview]
Message-ID: <20171214194025.21334-4-phil@nwl.cc> (raw)
In-Reply-To: <20171214194025.21334-1-phil@nwl.cc>

It may happen that 'perr' variable does not get initialized, so making
parameter 'err' point to it in any case is error-prone. Avoid this by
initializing 'perr' upon declaration.
