[PATCH 6.12 056/869] drm/i915/gmbus: convert to struct intel_display

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jani Nikula <jani.nikula@intel.com>

[ Upstream commit fdc387383ebd0d88dda9c40bcb81023a70b4408e ]

struct intel_display will replace struct drm_i915_private as the main
device pointer for display code. Switch gmbus code over to it.
