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>
