of: fdt: remove unnecessary codes
While unflattening the device tree, we try to populate dt nodes and
properties into tree-shaped data structure.
In populate_properties function, pprev is initially set to
&np->properties, and then updated to &pp->next.
In both scenarios *pprev is NULL, since the memory area that we are
allocating from is initially zeroed.
I tested the code as below, and it showed that BUG was never called.
- if (!dryrun)
+ if (!dryrun) {
+ if (*pprev)
+ BUG();
*pprev = NULL;
+ }
Let's remove unnecessary code.
