Subject[PATCH] locking/lockdep: remove print_lock_trace function
Date
gcc warns that function print_lock_trace() is unused if
CONFIG_PROVE_LOCKING isn't set.

../kernel/locking/lockdep.c:2820:13: warning: ‘print_lock_trace’ defined
but not used [-Wunused-function]
static void print_lock_trace(struct lock_trace *trace, unsigned int
spaces)

Rework so we remove the function if CONFIG_PROVE_LOCKING isn't set.

Fixes: c120bce78065 ("lockdep: Simplify stack trace handling")
