Subject: [ 26/47] mtd: nand: fix scan_read_raw_oob

3.0-stable review patch.  If anyone has any objections, please let me know.

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

From: Dmitry Maluka <D.Maluka@...global.com>

commit 34a5704d91d6f8376a4c0a0143a1dd3eb3ccb37e upstream.

It seems there is a bug in scan_read_raw_oob() in nand_bbt.c which
should cause wrong functioning of NAND_BBT_SCANALLPAGES option.

Artem: the patch did not apply and I had to amend it a bit.
