Please move your extern into <sata.h>, as the starting point before
merge.  If you could also go and fix:
$ git grep -l sata_dev_desc
common/cmd_sata.c
drivers/block/ata_piix.c
drivers/block/dwc_ahsata.c
drivers/block/dwc_ahsata.h
drivers/block/fsl_sata.c
drivers/block/pata_bfin.c
drivers/block/pata_bfin.h
drivers/block/sata_dwc.c
drivers/block/sata_sil.c
drivers/block/sata_sil.h
drivers/block/sata_sil3114.c

To use <sata.h> (some already do) instead of their own private extern
I'd greatly appreciate it.
