lockdep: fix unused function warning in kernel/lockdep.c
Impact: fix build warning this warning: kernel/lockdep.c:584: warning: ‘print_lock_dependencies’ defined but not used triggers because print_lock_dependencies() is only used if both CONFIG_TRACE_IRQFLAGS and CONFIG_PROVE_LOCKING are enabled. But adding #ifdefs is not an option here - it would spread out to 4-5 other helper functions and uglify the file. So mark this function as __used - it's static and the compiler can eliminate it just fine. Signed-off-by: Ingo Molnar <mingo@elte.hu>
