Subject: [PATCH v3 3/5] ocxl: read_pasid never returns an error, so make it void
Date: Wed, 20 Mar 2019 16:34:46 +1100 [thread overview]
Message-ID: <20190320053448.2098-4-alastair@au1.ibm.com> (raw)
In-Reply-To: <20190320053448.2098-1-alastair@au1.ibm.com>
From: Alastair D'Silva <alastair@d-silva.org>
No need for a return value in read_pasid as it only returns 0.
