Subject: [29/91] ARM: Fix gen_nand probe structures contents

2.6.34-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Marek Vasut <marek.vasut@...il.com>

commit ef077179a2909d3d0d3accf29ad1ea9ebb19019b upstream.

These three platforms didn't properly fill nr_chips in gen_nand
registration and therefore depended on gen_nand bug fixed by commit
81cbb0b17796d81cbd92defe113cf2a7c7a21fbb ("mtd: gen_nand: fix support for
multiple chips")
