Subject: [PATCH v3 0/6] panic: sys_info: Refactor and fix a potential issue

While targeting the compilation issue due to dangling variable,
I have noticed more opportunities for refactoring that helps to
avoid above mentioned compilation issue in a cleaner way and
also fixes a potential problem with global variable access.
Please, give it a try.

Changelog v3:
- addressed an issue with empty parameter returned (Feng)
- gathered tags (Feng)

Changelog v2:
v2: https://lore.kernel.org/r/20251029111202.3217870-2-andriy.shevchenko@linux.intel.com

- addressed an issue when converting to match_string() (Feng)
- Cc'ed to Petr (requested by Feng)
