Subject: [PATCH 1/2] tools/lib/lockdep: Add missing declaration of 'pr_cont()'

From: Mengting Zhang <zhangmengting@...wei.com>

An annoying compile warning due to missing declaration is shown below:
In file included from lockdep.c:27:0:
../../../kernel/locking/lockdep.c: In function 'print_unlock_imbalance_bug' :
../../../kernel/locking/lockdep.c:3544:2: warning: implicit declaration of function 'pr_cont' [-Wimplicit-function-declaration]
  pr_cont(") at:\n");
  ^
Adding the declaration of 'pr_cont' fixes the problem.
