| |
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthias Fend <Matthias.Fend@wolfvision.net>
commit eb9c5836384cd2a276254df6254ed71117983626 upstream.
The out functions should only handle actual available data instead of the complete buffer. Otherwise for example the ep0_consume function will report ghost events since it tries to decode the complete buffer - which may contain partly invalid data.
