[dvblast-devel] Simple change for better human reading ...

[Thomas Kernen]

Unless mistaken I believe there was a long list of commits in LinuxTV 
drivers a couple of months or so ago to start fixing this (linked to the 
move from DVBv3 to DVBv5 API). But I don't think we can claim that there 
will be consistency across all chipsets and implementations.
