From: Bartlomiej Zolnierkiewicz <bzolnier@...il.com>
Subject: [PATCH v2] pata_it8213: fix register naming used in it8213_set_piomode()
Rename 'idetm_port' and 'idetm_data' variables to 'master_port'
and 'master_data' respectively to match register naming used in
it8213_set_dmamode() and in ata_piix.c.
Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@...il.com>

v2: don't change master_port type
