Subject: [PATCH] drm/i915: Rename global latency_ns variable
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

We use the variable name latency_ns in both the local lowlevel wm
calculation routines and at the global level. Rename the global value to
reduce shadow warnings and future confusion.
