fdt: fix 'prop (...) not found!' error in 'fdt set' command
This commit brings things back to the well known working state of the command. - With commit 9620d87259572ef21f0df60988d9a932ca673779 (cmd/fdt: support single value replacement within an array) there was an error introduced modifying (inserting) a property to a device-tree node. fdt_getprop(...) returnes a len with -1 for a non-existing property, but a memcpy with len -1 isn't a good idea and things went wrong (crash). - Some times later Tom did repair this with commit 99bb38e2cce9d99238458e0f6d1880c6d2e80a4d (fdt: Check for NULL return from fdt_getprop in 'fdt set') This repairs the crash but the behaviour of the command isn't like before, it makes it impossible to insert a property. - Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at> Acked-by: Simon Glass <sjg@chromium.org>
