Subject: RE: [PATCH 1/2] ahci: qoriq: add lx2160 platforms support

Hi Jens，

	I send the sata patchs to the upstream patchwork with ./scripts/get_maintainer.pl, but I find my patch on http://patchwork.ozlabs.org/project/linux-ide/list/ , I saw the MAINTAINERS, the driver/ata/* should be on https://patchwork.kernel.org/project/linux-block/list/ . could you please help me what the patchwork is right.
	Thanks a lot.

Best Regards,
Peng
