| Subject: lib/oid_registry.c: remove redundant assignment to variable num |
| Date: Mon, 17 Oct 2022 22:45:56 +0100 |
| |
| The variable num is being assigned a value that is never read, it is being |
| re-assigned a new value in both paths if an if-statement. The assignment |
| is redundant and can be removed. |
| |
| Cleans up clang scan build warning: |
| lib/oid_registry.c:149:3: warning: Value stored to 'num' is |
| never read [deadcode.DeadStores] |
