From 6a98560755636b07ca54bf9cea6435b8e82b57d5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 20 Mar 2023 22:33:47 +0200 Subject: [PATCH] drm/i915: Generalize planes_{enabling,disabling}() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit I want to use the same logic that planes_{enabling,disabling}() are using for other features as well. Generlize the thing into a pair of macros.
