mtd: mtdchar: add missing initializer on raw write
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> Signed-off-by: Peter Wippich <> Tested-by: Ricard Wanderlof <> Signed-off-by: Artem Bityutskiy <> Signed-off-by: Greg Kroah-Hartman <>
