Subject: [PATCH] devargs: Fix rte_devargs_parse uninitialized calls
Date: Thu, 10 Feb 2022 18:01:31 +0100	[thread overview]
Message-ID: <20220210170131.2199922-1-grive@u256.net> (raw)
In-Reply-To: <20220210071052.527-1-madhuker.mythri@oracle.com>

The function rte_devargs_parse() previously was safe to call with
non-initialized devargs structure as parameter.

When adding the support for the global device syntax,
this assumption was broken. Restore it by forcing memset as part of
the call itself.

Bugzilla Id: 933
Fixes: b344eb5d941a ("devargs: parse global device syntax")
