1186 Although std_id is 64 bits, there is an issue on PPC32 architecture that
1187 makes switch(__u64) to break. So, there's a hack on v4l2-common.c rounding
1188 this value to 32 bits.
1189 As, currently, the max value is for V4L2_STD_ATSC_16_VSB (30 bits wide),
1190 it should work fine. However, if needed to add more than two standards,
1191 v4l2-common.c should be fixed.
