commit ddd068d81445b17ac0bed084dfeb9e58b4df3ddd upstream.
Declare ftrace_get_parent_ra_addr() as static to suppress clang compiler warning that 'no previous prototype'. This function is not intended to be called from other parts.
Fix follow error with clang-19:
arch/mips/kernel/ftrace.c:251:15: error: no previous prototype for function 'ftrace_get_parent_ra_addr' [-Werror,-Wmissing-prototypes] 251 | unsigned long ftrace_get_parent_ra_addr(unsigned long self_ra, unsigned long | ^ arch/mips/kernel/ftrace.c:251:1: note: declare 'static' if the function is not intended to be used outside of this translation unit 251 | unsigned long ftrace_get_parent_ra_addr(unsigned long self_ra, unsigned long | ^ | static 1 error generated.
