Subject: [PATCH v2 2/4] lockdep: make MAX_LOCKDEP_SUBCLASSES unconditionally visible
Date: Fri, 16 Sep 2016 18:02:43 +0200 [thread overview]
Message-ID: <1474041765-17818-3-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1474041765-17818-1-git-send-email-bgolaszewski@baylibre.com>
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.
