2.6.28-stable review patch. If anyone has any objections, please let us know.
------------------
From: Sergei Shtylyov <sshtylyov@ru.mvista.com>
commit a509538d4fb4f99cdf0a095213d57cc3b2347615 upstream.
Commit 9567b349f7e7dd7e2483db99ee8e4a6fe0caca38 (ide: merge ->atapi_*put_bytes and ->ata_*put_data methods) introduced a regression WRT the odd-length ATAPI PIO transfers -- the final word didn't get written (causing command timeouts).
