From 04dd7c8e5624ee971004a6b310c2e7d958a0018c Mon Sep 17 00:00:00 2001 From: Xiang W <wxjstz@126.com> Date: Mon, 29 Aug 2022 07:53:15 +0800 Subject: [PATCH] virtio: pci: fix bug of virtio_pci_map_capability The bar of the structure virtio_pci_cap is the index, and each base address occupies 4 bytes, so it needs to be multiplied by 4.
