My bad, I mistakenly "compile-tested" this with a defconfig that doesn't
enable CONFIG_OF_LIBFDT_OVERLAY so this was never built.
The compiler is actually not happy about that, it wants it cast to (char
**).
@Marek, what do you prefer? We go back to having of_flat_tree a char* or
do the cast in boot_relocate_fdt?
What about -- go back and add a code comment ?
btw. please try and clip the response using [...] so you won't be
quoting a wall of useless text each time. The actual response is then
hard to find in it.
