Subject: [PATCH] USB: ftdi_sio: fix error message on close
Date: Sun, 22 Nov 2009 17:01:13 +0100 [thread overview]
Message-ID: <1258905673-6885-1-git-send-email-jhovold@gmail.com> (raw)
Resubmitting read urb fails with -EPERM if completion handler runs while
urb is being killed on close. This should not be reported as an error.
