-stable review patch. If anyone has any objections, please let us know.
------------------
From: Benjamin Herrenschmidt <[email protected]>
patch a87a87ccdc541e0a0cc8c7d01a365be8d9153a7b in mainline.
The siimage 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.
