[PATCH 05/12] drm/i915: Protect lockdep functions with #ifdef

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



With upcoming lock tracepoints config, it'd define some of lockdep
functions without enabling CONFIG_LOCKDEP actually.  The existing code
assumes those functions will be removed by the preprocessor but it's
not the case anymore.  Let's protect the code with #ifdef's explicitly.
