Subject: [43/54] mtd: gen_nand: fix support for multiple chips

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

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

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

commit 81cbb0b17796d81cbd92defe113cf2a7c7a21fbb upstream.

This patch corrects a problem where gen_nand driver assumed there can be only
one chip and ignored the pdata->chip.nr_chips value.
