David Gibson 7d8ef6e1db tests: Correct fdt handling of overlays without fixups and base trees without symbols ... The fdt_overlay_apply() function purports to support the edge cases where an overlay has no fixups to be applied, or a base tree which has no symbols (the latter can only work if the former is also true). However it gets it wrong in a couple of small ways: * In the no fixups case, it doesn't fail immediately, but will attempt fdt_for_each_property_offset() giving -FDT_ERR_NOTFOUND as the node offset, which will fail. Instead it should succeed immediately, since there's nothing to do. * In the case of no symbols, it again doesn't fail immediately. However if there is an actual fixup it will fail with an unexpected error, because -FDT_ERR_NOTFOUND is passed to fdt_getprop() when attempting to look up the symbols. We should instead return -FDT_ERR_NOTFOUND directly. Both of these errors lead to the code returning misleading error codes in failing cases.
