mtd: mtdchar: add missing initializer on raw write
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 <pewi@gw-instruments.de> Cc: stable@kernel.org Tested-by: Ricard Wanderlof <ricardw@axis.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
