PATCH 1/1 libata: make ata_sff_data_xfer_noirq() work with 32-bit PIO

From: Bartlomiej Zolnierkiewicz <[email protected]>
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.
