Subject: [PATCH 13/31] crypto: qat - remove writes into WQCFG
Date: Mon, 12 Oct 2020 21:38:29 +0100 [thread overview]
Message-ID: <20201012203847.340030-14-giovanni.cabiddu@intel.com> (raw)
In-Reply-To: <20201012203847.340030-1-giovanni.cabiddu@intel.com>
WQCFG registers contain the correct values after reset in all
generations of QAT. No need to write into them.
