Subject: [Intel-gfx] [PATCH 14/22] drm/i915/gt: Use built-in active intel_context reference
Date: Wed, 20 May 2020 08:54:55 +0100	[thread overview]
Message-ID: <20200520075503.10388-14-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20200520075503.10388-1-chris@chris-wilson.co.uk>

Since a few rearragements ago, we have an explicit reference to the
containing intel_context from inside the active reference and can drop
our own reference handling dancing around releasing the i915_active.
