For menuconfig and nconfig, it's a subtle difference. The following menu items are indented more after the patch (i.e., they are not indented enough before the patch): │ <M> Enable KVM host support Intel GVT-g graphics virtualization │ │ [*] Enable Intel PXP support │ │ drm/i915 Debugging ---> │ │ drm/i915 Profile Guided Optimisation ---> Same menu items for gconfig: they should all be subordinate (so indented) to the main <M> Intel 8xx/9xx/G3x/G4x/HD Graphics menu. For xconfig, it's worse. "drm/i915 Debugging" and "drm/i915 Profile Guided Optimisation" are shown on the left side window, while are of the other i915 options are shown in the right side window (before the patch). After the patch, all subordinate options are listed in the right side window under the main "Intel 8xx/9xx/G3x/G4x/HD Graphics" menu item. See attached photos for comparisons.

Inserting a Kconfig symbol that does not have a dependency (DRM_I915_GVT) into a list of other symbols that do have a dependency (on DRM_I915) breaks the driver menu presentation in 'make *config'. Relocate the DRM_I915_GVT symbol so that it does not cause this problem.
