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.
