You explain why you need to rename the header, and thats what you do in
this patch. On the other hand, you also move the freq_clip_table
structure definition. This change is present in this patch, I dont see
the connection with the file rename, and you also do not explain why it
is needed. Can you please consider, either split this change to other
(new) patch or explain it also in this patch?
