Subject: [PATCH v5 12/29] baseband/acc100: add protection for NULL HARQ input
Date: Thu, 20 Oct 2022 22:20:45 -0700 [thread overview]
Message-ID: <20221021052102.107141-13-hernan.vargas@intel.com> (raw)
In-Reply-To: <20221021052102.107141-1-hernan.vargas@intel.com>
It is possible to cause an invalid HW operation in case the user
provides the BBDEV API and HARQ operation with input enabled and zero
input. Adding protection for that case.
Fixes: 5ad5060f8f7 ("baseband/acc100: add LDPC processing functions")
