Subject: ide-disk: use ata_id_hpa_enabled()
X-Git-Tag: v2.6.28-rc1~710^2~62
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=f41891c134ccdd07583ebd8d4af7fed883375672;p=linux-2.6-omap-h63xx.git

ide-disk: use ata_id_hpa_enabled()

idedisk_supports_hpa() -> ata_id_hpa_enabled().

The latter one also checks validity of words 82 & 85.
