hw-breakpoints: fix undeclared ksym_tracer_mutex
ksym_tracer_mutex is declared inside an #ifdef CONFIG_PROFILE_KSYM_TRACER
section. This makes it unavailable for the hardware breakpoint tracer if it is
configured without the breakpoint profiler.
This patch fixes the following build error:
kernel/trace/trace_ksym.c: In function ‘ksym_trace_filter_read’:
kernel/trace/trace_ksym.c:226: erreur: ‘ksym_tracer_mutex’ undeclared (first use in this function)
kernel/trace/trace_ksym.c:226: erreur: (Each undeclared identifier is reported only once
kernel/trace/trace_ksym.c:226: erreur: for each function it appears in.)
kernel/trace/trace_ksym.c: In function ‘ksym_trace_filter_write’:
kernel/trace/trace_ksym.c:273: erreur: ‘ksym_tracer_mutex’ undeclared (first use in this function)
kernel/trace/trace_ksym.c: In function ‘ksym_trace_reset’:
kernel/trace/trace_ksym.c:335: erreur: ‘ksym_tracer_mutex’ undeclared (first use in this function)
