| Subject: mtd: mtdchar: add missing initializer on raw write |
| |
| From: Peter Wippich <pewi@gw-instruments.de> |
| |
| commit bf5140817b2d65faac9b32fc9057a097044ac35b upstream. |
| |
| On writes in MODE_RAW the mtd_oob_ops struct is not sufficiently |
| initialized which may cause nandwrite to fail. With this patch |
| it is possible to write raw nand/oob data without additional ECC |
| (either for testing or when some sectors need different oob layout |
| e.g. bootloader) like |
| nandwrite -n -r -o /dev/mtd0 <myfile> |
