UBI: add ioctl for map operation
This patch adds ioctl for the LEB map operation (as a debugging option so far). [Re-named ioctl to make it look the same as the other one and made some minor stylistic changes. Artem Bityutskiy.] Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
