staging: usbip: bugfix for stack corruption on 64-bit architectures
Previously a 6 byte array (buf) was erroneously cast to a 8 byte long (event_bits) on 64-bit architectures which caused a stack corruption. Signed-off-by: Bart Westgeest <bart@elbrys.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
