Hi Maintainer,
Can you take the patch which is needed by some new platforms?
Thanks

I think you've got the wrong guy. Here's how you can find out who the
maintainer is:
So your patch is against drivers/ata/ata_piix.c. So you do:
$ ./scripts/get_maintainer.pl -f drivers/ata/ata_piix.c
Jeff Garzik <[email protected]> (supporter:SERIAL ATA (SATA)...)
[email protected] (open list:SERIAL ATA (SATA)...)
[email protected] (open list)
And this is the CC list you can use to send the patch to.
HTH.
