| Subject: mtd: mtdconcat: fix NAND OOB write |
| |
| From: Felix Radensky <felix@embedded-sol.com> |
| |
| commit 431e1ecabddcd7cbba237182ddf431771f98bb4c upstream. |
| |
| Currently mtdconcat is broken for NAND. An attemtpt to create |
| JFFS2 filesystem on concatenation of several NAND devices fails |
| with OOB write errors. This patch fixes that problem. |
