Subject: [Intel-gfx] [PATCH v2 rebased 3/6] drm/i915: Only initialize dlk phy lock in display 12 and newer
Date: Thu,  6 Apr 2023 07:31:30 -0700	[thread overview]
Message-ID: <20230406143133.29474-3-jose.souza@intel.com> (raw)
In-Reply-To: <20230406143133.29474-1-jose.souza@intel.com>

This spin lock will not be used in older display versions, so no need
to initialize it.
