From: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx> Subject: [PATCH] pata_efar: fix register naming used in efar_set_piomode() Rename 'idetm_port' and 'idetm_data' variables to 'master_port' and 'master_data' respectively to match register naming used in efar_set_dma_mode() and in ata_piix.c. Fix efar_set_piomode() documentation and 'master_port' type while at it.
