## ERRORS

None.

## WARNINGS

None.

## INFO

**Compiler warning suppression via NULL initialization**

The patch initializes `rsp` and `rsp_cn20k` to NULL to satisfy the compiler's uninitialized variable analysis. This is a valid fix for the warning, though it relies on the assumption that the existing branch logic guarantees one of the pointers will be set before the read. The NULL initialization does not add runtime overhead or correctness burden -- if the logic is wrong, a NULL dereference will occur deterministically rather than silently using stack garbage.

The fix is correct. The warning is a static analysis limitation, not a real bug (the code branches that set the pointer and the branches that read it are controlled by the same condition).

Review-Result: CLEAN
