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.
