From: Arnd Bergmann <arnd at arndb.de>
It appears that a merge conflict ended up hiding a newly added constant
in some configurations:
arch/arm64/kernel/entry-ftrace.S: Assembler messages:
arch/arm64/kernel/entry-ftrace.S:59: Error: undefined symbol FTRACE_OPS_DIRECT_CALL used as an immediate value
FTRACE_OPS_DIRECT_CALL is still used when CONFIG_DYNAMIC_FTRACE_WITH_DIRECT_CALLS
is enabled, even if CONFIG_FUNCTION_GRAPH_TRACER is disabled, so change the
ifdef accordingly.
Fixes: 3646970322464 ("arm64: ftrace: Enable HAVE_FUNCTION_GRAPH_RETVAL")
