Subject[PATCH 3.13 132/172] mtd: nand: omap: fix ecclayout->oobfree->length
Date
3.13-stable review patch.  If anyone has any objections, please let me know.

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

From: Pekon Gupta <pekon@ti.com>

commit bb38eefb6858ce16b34716145b9597a5680aa54c upstream.

This patch excludes reserved-marker byte-position from oobfree->length
calculation. Thus all bytes from oobfree->offset till end of OOB are free.
