| Subject: mtd: nand: omap: fix ecclayout->oobfree->length |
| |
| 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. |
