Subject: USB: keyspan: fix overrun-error reporting
From: Johan Hovold <[email protected]>
commit 855515a6d3731242d85850a206f2ec084c917338 upstream.
Fix reporting of overrun errors, which are not associated with a
character. Instead insert a null character and report only once.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
