File 0028-usb-redir-Don-t-try-to-write-to-the-chardev-after-a-.patch of Package qemu
>From 7e49ff036892fade86c7734118ee0c6da5cbad09 Mon Sep 17 00:00:00 2001 From: Hans de Goede <hdegoede@redhat.com> Date: Thu, 11 Aug 2011 12:11:16 +0200 Subject: [PATCH 28/28] usb-redir: Don't try to write to the chardev after a close event Sicne we handle close async in a bh, do_write and thus write can get called after receiving a close event. This patch adds a check to the usb-redir write callback to not do a qemu_chr_write on a closed chardev.
