Subject: [PATCH 17/19] hw/cxl/type3: Cleanup multiple CXL_TYPE3() calls in read/write functions
Date: Mon, 25 Sep 2023 17:11:22 +0100	[thread overview]
Message-ID: <20230925161124.18940-18-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20230925161124.18940-1-Jonathan.Cameron@huawei.com>

From: Gregory Price <gourry.memverge@gmail.com>

Call CXL_TYPE3 once at top of function to avoid multiple invocations.
