From 958349ff710b79d85f35be73d1b09991f67b3423 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 16 Sep 2022 19:52:05 +0300 Subject: [PATCH] drm/i915/fbc: Remove stale FIXME MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Remove the old tales about 90/270 degree rotation effectively preventing FBC. That hasn't been true since we stopped demanding the fence is present in commit 691f7ba58d52 ("drm/i915/display/fbc: Make fences a nice-to-have for GEN9+") Also fix up the multiline comment formatting while at it.
