Subject: [PATCH qemu 2/5] hw/mem/cxl_type3: Add paired msix_uninit_exclusive_bar() call
Date: Mon, 3 Feb 2025 16:19:05 +0000 [thread overview]
Message-ID: <20250203161908.145406-3-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20250203161908.145406-1-Jonathan.Cameron@huawei.com>
From: Li Zhijian <lizhijian@fujitsu.com>
msix_uninit_exclusive_bar() should be paired with msix_init_exclusive_bar()
Ensure proper resource cleanup by adding the missing
`msix_uninit_exclusive_bar()` call for the Type3 CXL device.
