From 20bea20a550a4343cdf473148372bd6a91369614 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 15 Mar 2022 15:59:55 +0200 Subject: [PATCH] drm/i915/fbc: Eliminate possible_framebuffer_bits MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Not sure what the point of this fbc->possible_frontbuffer_bits is. And especially don't see why it's returning all the bits when fbc is not even enabled. So let's just get rid of this and only say we are interested in the plane's frontbuffer bits when fbc is actually enabled.
