 647    Although std_id is 64 bits, there is an issue on PPC32 architecture that

 649    this value to 32 bits.
 650    As, currently, the max value is for V4L2_STD_ATSC_16_VSB (30 bits wide),
 651    it should work fine. However, if needed to add more than two standards,
 652    v4l2-common.c should be fixed.
