Subject: lockdep: Actually _dec_ in debug_atomic_dec
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=fa9a97dec611c5356301645d576b523ce3919eba;p=deliverable%2Flinux.git

lockdep: Actually _dec_ in debug_atomic_dec

Fix a silly copy-paste mistake that was making debug_atomic_dec use
this_cpu_inc instead of this_cpu_dec.
