[PATCH v2 0/6] panic: sys_info: Refactor and fix a potential issue

From: Andy Shevchenko

Date: Wed Oct 29 2025 - 07:12:42 EST


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 v2:
- rebased on top of the current codebase
- addressed an issue when converting to match_string() (Feng)
- Cc'ed to Petr (requested by Feng)

v1: https://lore.kernel.org/r/20250711095413.1472448-1-andriy.shevchenko@xxxxxxxxxxxxxxx
