| Subject: [PATCH] utilities: Fix build failure with -Werror=maybe-uninitialized |
| |
| Summary: |
| Initialize magic_number to zero to avoid such failure. |
| utilities/blob_db/blob_log_format.cc:91:3: error: 'magic_number' may be used |
| uninitialized in this function [-Werror=maybe-uninitialized] |
| if (magic_number != kMagicNumber) { |
