Subject: [PATCH] hw/block/nvme: fix bad clearing of CAP
Date: Tue, 8 Dec 2020 10:16:58 +0100 [thread overview]
Message-ID: <20201208091658.41820-1-its@irrelevant.dk> (raw)
From: Klaus Jensen <k.jensen@samsung.com>
Commit 37712e00b1f0 ("hw/block/nvme: factor out pmr setup") changed the
control flow such that the CAP register is erronously cleared after
nvme_init_pmr() has configured it. Since the entire NvmeCtrl structure
is zero-filled initially, there is no need for the explicit clearing, so
just remove it.
Fixes: 37712e00b1f0 ("hw/block/nvme: factor out pmr setup")
