nvmem: mxs-ocotp: fix buffer overflow in read
This patch fixes the issue where the mxs_ocotp_read is reading the ocotp in reg_size steps but decrements the remaining size by 1. The number of iterations is thus four times higher, overwriting the area behind the output buffer. Fixes: c01e9a11ab6f ("nvmem: add driver for ocotp in i.MX23 and i.MX28") Tested-by: Stefan Wahren <stefan.wahren@i2se.com> Signed-off-by: Stanislav Meduna <stano@meduna.org> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
