From 15d8061bf02aa299b2447f7a22fd18b4a503ea9d Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 19 Oct 2007 00:30:05 +0200 Subject: [PATCH] ide: Fix cs5535 driver accessing beyond array boundary The cs5535 uses an incorrect construct to access the other drive of a pair, causing it to access beyond an array boundary on the secondary interface. This fixes it by using the new ide_get_paired_drive() helper instead.
