Date: Thu, 13 Oct 2011 15:04:43 +0200 From: Bartlomiej Zolnierkiewicz <bzolnier@...il.com> To: Jeff Garzik <jgarzik@...ox.com> Cc: linux-ide@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] libata: make ata_sff_data_xfer_noirq() work with 32-bit PIO From: Bartlomiej Zolnierkiewicz <bzolnier@...il.com> Subject: [PATCH] libata: make ata_sff_data_xfer_noirq() work with 32-bit PIO Always use ata_sff_data_xfer32() in ata_sff_data_xfer_noirq() so the latter can be also used for host controllers supporting 32-bit PIO operations. It is a completely safe thing to do because if 32-bit PIO is not supported or enabled ata_sff_data_xfer32() will fallback to a standard method.
