2.6.31-stable review patch. If anyone has any objections, please let us know. ------------------ From: Joris van Rantwijk commit 63a9609513007537a0b23ac511fd73f9bd609ea0 upstream. The generic usbserial driver in Linux 2.6.31 halts its receiving channel in response to throttle requests from the line discipline. Unfortunately it drops the contents of the first URB received after throttling takes effect. This patch corrects that problem.
