Starting commented lines in a file mostly contains comments describing
license, copyright or general information about the file.
E.g., in sound/pci/ctxfi/ctresource.c, initial comment lines describe
its copyright and other related file informations.
But as kernel-doc reads these lines, it results in ineffective warnings by
kernel-doc, related to these.
Provide a simple fix by skipping first three lines in a file for checking
kernel-doc comments.
