From bf5140817b2d65faac9b32fc9057a097044ac35b Mon Sep 17 00:00:00 2001 From: Peter Wippich Date: Mon, 6 Jun 2011 15:50:58 +0200 Subject: [PATCH] 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 Signed-off-by: Peter Wippich Cc: stable@kernel.org Tested-by: Ricard Wanderlof Signed-off-by: Artem Bityutskiy --- drivers/mtd/mtdchar.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/mtd/mtdchar.c b/drivers/mtd/mtdchar.c index f1af2228a1b1..49e20a497084 100644 --- a/drivers/mtd/mtdchar.c +++ b/drivers/mtd/mtdchar.c @@ -320,6 +320,7 @@ static ssize_t mtd_write(struct file *file, const char __user *buf, size_t count ops.mode = MTD_OOB_RAW; ops.datbuf = kbuf; ops.oobbuf = NULL; + ops.ooboffs = 0; ops.len = len; ret = mtd->write_oob(mtd, *ppos, &ops); -- 2.34.1
