From 6bd36e0822ca841bbb21d050e80cd690209bd322 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= <ville.syrjala@linux.intel.com> Date: Wed, 7 Nov 2018 19:18:21 +0200 Subject: [PATCH] drm/i915: Switch LSPCON to PCON mode if it's in LS mode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We no longer change LSPCON into PCON mode if it boots up in LS mode. This was broken by some code shuffling in commit 96e35598cead ("drm/i915: Check LSPCON vendor OUI"). I actually can't see a reason why that code shuffling had to be done. The commit msg notes it but doesn't justify it in any way. But I guess we'll keep the code in its current place anyway and just make the "switch to PCON mode" part effective once again.
