From 8d9d2a723d64b650f2e6423024ccb4a33f0cdc40 Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Mon, 7 Feb 2022 15:27:00 +0200 Subject: drm/i915: Fix mbus join config lookup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The bogus loop from compute_dbuf_slices() was copied into check_mbus_joined() as well. So this lookup is wrong as well. Fix it.
