-stable review patch. If anyone has any objections, please let us know.
------------------
From: Benjamin Herrenschmidt <[EMAIL PROTECTED]>
patch 15d8061bf02aa299b2447f7a22fd18b4a503ea9d in mainline.
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.
