Subject: [PATCH v2 01/10] baseband/acc: fix access to deallocated mem
Date: Thu,  3 Oct 2024 13:49:03 -0700	[thread overview]
Message-ID: <20241003204912.131319-2-hernan.vargas@intel.com> (raw)
In-Reply-To: <20241003204912.131319-1-hernan.vargas@intel.com>

Prevent op_addr access during queue_stop operation, as this memory may
have been deallocated.

Fixes: e640f6cdfa84 ("baseband/acc200: add LDPC processing")
Cc: stable@dpdk.org
