Normalized line endings (no changes)

Normalized line endings by touching (touch) the dsp files, no changes to
the files were made.
This is in order so we can see actual modified lines in case s.o. modifies
the files.
The files will have CRLF as EOL on checkout due to the .gitattributes
setting.
