flash_otp_write: fix writing to NAND in presence of partial reads
When doing something like: { printf "\xff"; printf "\xfe"; } | flash_otp_write -u /dev/mtd0 0 flash_otp_write might see only a single byte when reading from stdin for the first tim. In this case (and without this patch) it pads to $writesize with '\xff's and writes that out. In the next iteration it reads the 2nd byte, pads and writes again. So the 2nd byte is written to offset $writesize instead of 1. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
