Subject: [PATCH v2 37/37] baseband/acc100: reset pointer after rte_free
Date: Fri, 19 Aug 2022 19:31:57 -0700 [thread overview]
Message-ID: <20220820023157.189047-38-hernan.vargas@intel.com> (raw)
In-Reply-To: <20220820023157.189047-1-hernan.vargas@intel.com>
Set local pointer to NULL after rte_free.
This needs to be set explicitly since logic may check for null pointers.
Fixes: 060e7672930 ("baseband/acc100: add queue configuration")
Cc: stable@dpdk.org
