lockevent_read() has a __weak definition and the only caller in kernel/locking/lock_events.c, plus a strong definition in qspinlock_stat.h that overrides it, but no other declaration. This causes a W=1 warning: kernel/locking/lock_events.c:61:16: error: no previous prototype for 'lockevent_read' [-Werror=missing-prototypes] Add shared prototype to avoid the warnings.
