From 1b9e665064c6fad91f4265743555406f5804dbcb Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Wed, 29 Jun 2016 16:09:29 +0100 Subject: [PATCH] drm/i915: Compact Gen8 semaphore initialization Replace the macro initializer with a programatic loop which results in smaller code and hopefully just as clear. v2: Rebase.
