Subject: [PATCH v2 4/4] [libata] pata_platform: s/ioport_shift/reg_shift/g

From: Anton Vorontsov <[email-masked]>
Date: Tue, 4 Dec 2007 20:07:45 +0300

This patch renames ioport_shift member of pata_platform_info
structure to reg_shift. Users of pata_platform are followed
appropriately.

Rationale of that change is: shifting applies to the whole memory
mapped region, not only to the command block of the ATA registers,
despite the fact that shifting is meaningless for ctl register.

This patch should make Sergei Shtylyov a bit more happy. ;-)
