From d5a1c36013ed1dc0d5f88332d10d353c204d63d3 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 25 Jun 2019 14:01:14 +0100 Subject: [PATCH] drm/i915: Rename intel_wakeref_[is]_active Our general rule is to use is/has as the verb for boolean functions, rename intel_wakeref_active to intel_wakeref_is_active so the question being asked is clear.
