powerpc/ftrace: Add prototype for prepare_ftrace_return() (b3a7864c) · Commits · 戴 / test

Sparse emits a warning: symbol 'prepare_ftrace_return' was not declared. Should it be static? prepare_ftrace_return() is called from assembler and should not be static. Add a prototype for it to asm-prototypes.h and include that in ftrace.c. Signed-off-by:
