// [TAG] - EIP 48169  
// [Category]- Enhancement
// [Severity]- Mordarate
// [Symptom]- Code Cleanup and Compiler Warning need to resolved.
// [Rootcause] Warnings reported when we build AMI higher Warning level.
// [Solution]- 1. Fix the warnings and do the code cleanup. 
//             2. Introduce proper checks.
//             3. change the popupSel.c to not change the Option/variable
// cache to default or first option
//                when the variable cache is not matching with any of
// option.
