+Subject: [PATCH] Revert "drm/i915: Enable GMBUS for post-gen2 chipsets"
+
+commit 826c7e4147f902737b281e8a5a7d7aa33fd63316 upstream.
+
+Revert commit 8f9a3f9b63b8cd3f03be9dc53533f90bd4120e5f. This fixes a
+hang when loading the eeprom driver (see bug #35572.) GMBUS will be
+re-enabled later, differently.
