If anyone has any objections, please let me know. ------------------ From: Abdun Nihaal commit 941eaf9a6d3b33dea49f2c0a1da7546a03b6ff71 upstream. The memory allocated for cmd is not freed after the call to kvaser_usb_send_cmd() in both the normal and error paths. Fix that by adding a kfree() immediately after the call.
