* codec: Fix the GSM 06.20 ordering tablesSylvain Munaut2013-03-011-41/+41
| | | | | | | | | | Seems the script I used to parse those had a bug where range of bits in the 'decreasing' direction ( like 6..0 ) were not processed properly. Thanks to Andreas for noticing this ! Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
