libfdt: Trivial cleanup for CHECK_HEADER)
Currently the CHECK_HEADER() macro is defined local to fdt_ro.c. However, there are a handful of functions (fdt_move, rw_check_header, fdt_open_into) from other files which could also use it (currently they open-code something more-or-less identical). Therefore, this patch moves CHECK_HEADER() to libfdt_internal.h and uses it in those places. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
