[PATCH v2 2/4] lockdep: make MAX_LOCKDEP_SUBCLASSES unconditionally visible

From: Bartosz Golaszewski
Date: Fri Sep 16 2016 - 12:04:17 EST


This define is needed by i2c_adapter_depth() to detect if we don't
exceed the maximum number of lock subclasses. Make it visible even
if lockdep is disabled.
