The conversion from DocBook lead into some conversion issues, basically due to the lack of proper support at kernel-doc. So, address them: - Now, the C files with the exported symbols also need to be added. So, all headers need to be included twice: one to get the structs/enums/.. and another one for the functions; - Notes should use the ReST tag, as kernel-doc doesn't recognizes it anymore; - Identation needs to be fixed, as ReST uses it to identify when a format "tag" ends. - kernel-doc doesn't escape things like *pointer, so we need to manually add a escape char before it. - On some cases, kernel-doc conversion requires violating the 80-cols, as otherwise it won't properly parse the source code.
