Please use more descriptive comments, because it is not clear what you
mean here. Maybe here you just cut a text...
It is so strange to cut such small amount of text and I does not have

Here is just a typo fixed for the ata_timing structure. This typo does
not have influence on the driver operation, but I do not like to leave
such a negligible problem as it is.
