Subject: [PATCH 23/31] crypto: qat - remove hardcoded bank irq clear flag mask
Date: Mon, 12 Oct 2020 21:38:39 +0100 [thread overview]
Message-ID: <20201012203847.340030-24-giovanni.cabiddu@intel.com> (raw)
In-Reply-To: <20201012203847.340030-1-giovanni.cabiddu@intel.com>
Replace hardcoded value of the bank interrupt clear flag mask with a
value calculated on the fly which is based on the number of rings
present in a bank. This is to support devices that have a number of
rings per bank different than 16.
