[Intel-gfx] [PATCH 1/2] drm/i915: Silence __iomem sparse warn

[Ville Syrjala]

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

We don't care about __iomem mismatch when dealing with error
pointers. Silence it with ERR_CAST().

drivers/gpu/drm/i915/display/intel_display.c:1896:21:    expected struct i915_vma *[assigned] vma
drivers/gpu/drm/i915/display/intel_display.c:1896:21:    got void [noderef] __iomem *[assigned] iomem
drivers/gpu/drm/i915/display/intel_display.c:1896:21: warning: incorrect type in assignment (different address spaces)
