| Subject: of: Fix missing memory initialization on FDT unflattening |
| |
| From: Grant Likely <grant.likely@linaro.org> |
| |
| commit 0640332e073be9207f0784df43595c0c39716e42 upstream. |
| |
| Any calls to dt_alloc() need to be zeroed. This is a temporary fix, but |
| the allocation function itself needs to zero memory before returning |
| it. This is a follow up to patch 9e4012752, "of: fdt: fix memory |
| initialization for expanded DT" which fixed one call site but missed |
| another. |
