Due to a line break, printf was accidentally called with three
arguments instead of two, causing a different output than before.
Fix it by splitting the printf command into two lines.
Fixes: 907053193a ("scripts/mkits.sh: replace echo -e with printf")

# U-Boot firmware supports the booting of images in the Flattened Image
|
|
# Tree (FIT) format. The FIT format uses a device tree structure to
|
|
# describe a kernel image, device tree blob, ramdisk, etc. This script
|
|
# creates an Image Tree Source (.its file) which can be passed to the
|
|
# 'mkimage' utility to generate an Image Tree Blob (.itb file). The .itb
|
|
# file can then be booted by U-Boot (or other bootloaders which support
|
|
# FIT images). See doc/uImage.FIT/howto.txt in U-Boot source code for
|
|
# additional information on FIT images.
