[PATCH] tests/plugin: prevent uninitialized warning |
Date: |
Thu, 6 Feb 2020 17:32:38 +0800 |
From: Chen Qun <address@hidden>
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);
