[Qemu-devel] [PATCH] usb:xhci:fix memory leak in usb_xhci_exit


From: 李强
Subject: [Qemu-devel] [PATCH] usb:xhci:fix memory leak in usb_xhci_exit
Date: Tue, 13 Sep 2016 05:22:27 +0000

If the xhci uses msix, it doesn't free the corresponding
memory, thus leading a memory leak issue. This patch avoid this.
