[ Upstream commit 250f5402e636a5cec9e0e95df252c3d54307210f ]
Fixes a bug revealed by -Wmissing-prototypes when
CONFIG_FUNCTION_GRAPH_TRACER is enabled but not CONFIG_DYNAMIC_FTRACE:
arch/parisc/kernel/ftrace.c:82:5: error: no previous prototype for 'ftrace_enable_ftrace_graph_caller' [-Werror=missing-prototypes]
82 | int ftrace_enable_ftrace_graph_caller(void)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
arch/parisc/kernel/ftrace.c:88:5: error: no previous prototype for 'ftrace_disable_ftrace_graph_caller' [-Werror=missing-prototypes]
