[PATCH 01/11] drm/i915: Decouple i915_gem_dumb_create() from the display a bit

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Pass the device argument as drm_device to intel_plane_fb_max_stride()
to decouple i915_gem_dumb_create() vs. the display code a bit.

xe currently doesn't even call this, but it probably should...
