From: Arnd Bergmann <arnd@arndb.de> This function is only used when CONFIG_TRACE_BRANCH_PROFILING is set, and the declaration is hidden behind this Kconfig symbol, which causes a warning if disabled: kernel/trace/trace_branch.c:205:6: error: no previous prototype for 'ftrace_likely_update' [-Werror=missing-prototypes] Move the declaration out of the #ifdef to avoid the warning.
