  Refer to afa_dev_cf_sata() on how it's done in really optimal way.

To what ? - there is no ata or afa_dev_cf_sata ?

   Very funny. Meant to be ata_dev_is_sata(), of course.

We don't have one of those either - do you mean ata_id_is_sata ? If so
then yes that looks like it might be slightly cleaner although its
probably one instruction difference from the .s files.

   That extra *if* cost more than instruction I think.

I'll redo it that way

   OK, just leave ata_dev_is_cfa() alone and rename the patch.

WBR, Sergei
