Subject: [PATCH v1 1/1] x86/bugs: Remove dead code which might prevent from building
Date: Fri, 24 Oct 2025 14:59:59 +0200 [thread overview]
Message-ID: <20251024125959.1526277-1-andriy.shevchenko@linux.intel.com> (raw)
Clang, in particular, is not happy about dead code:
arch/x86/kernel/cpu/bugs.c:1830:20: error: unused function 'match_option' [-Werror,-Wunused-function]
1830 | static inline bool match_option(const char *arg, int arglen, const char *opt)
| ^~~~~~~~~~~~
1 error generated.
Remove a leftover from the previous cleanup.
Fixes: 02ac6cc8c5a1 ("x86/bugs: Simplify SSB cmdline parsing")
