Subject: [PATCH v3 13/30] baseband/acc100: reset pointer after rte_free
Date: Tue, 11 Oct 2022 19:53:29 -0700	[thread overview]
Message-ID: <20221012025346.204394-14-hernan.vargas@intel.com> (raw)
In-Reply-To: <20221012025346.204394-1-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
