Subject: [PATCH 05/12] hw/cxl/mbox: Remove dead code
Date: Wed, 24 Jan 2024 12:40:53 +0000	[thread overview]

In-Reply-To: <20240124124100.8218-1-Jonathan.Cameron@huawei.com>

From: Davidlohr Bueso <dave@stgolabs.net>

Two functions were reported to have dead code, remove the bogus
branches altogether, as well as a misplaced qemu_log call.
