Subject: [PATCH v2 03/12] hw/pci-bridge/cxl_upstream: Drop g_malloc() failure handling
Date: Fri, 26 Jan 2024 12:01:23 +0000	[thread overview]
Message-ID: <20240126120132.24248-4-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20240126120132.24248-1-Jonathan.Cameron@huawei.com>

As a failure of g_malloc() will result in QEMU exiting, it
won't return a NULL to check.  As such, drop the incorrect handling
of such NULL returns in the cdat table building code.
