Subject: [PATCH  v2 12/19] tests/plugin: prevent uninitialized warning
Date: Thu, 13 Feb 2020 22:51:02 +0000	[thread overview]
Message-ID: <20200213225109.13120-13-alex.bennee@linaro.org> (raw)
In-Reply-To: <20200213225109.13120-1-alex.bennee@linaro.org>

From: Chen Qun <kuhn.chenqun@huawei.com>

According to the glibc function requirements, we need initialise
 the variable. Otherwise there will be compilation warnings:

glib-autocleanups.h:28:3: warning: ‘out’ may be
used uninitialized in this function [-Wmaybe-uninitialized]
   g_free (*pp);
   ^~~~~~~~~~~~
