linux-can-fixes-for-3.14-20140212 Marc Kleine-Budde says: ==================== this is a pull request with one patch for net/master, for the current release cycle. Olivier Sobrie noticed and fixed that the kvaser_usb driver doesn't check the number of channels value from the hardware, which may result in writing over the bounds of an array in the driver. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
