| H A D | i915_vma.c | d976521a Fri Jun 10 07:12:04 CDT 2022 CQ Tang <cq.tang@intel.com> drm/i915: extend i915_vma_pin_iomap()
In the future display might try call this with a normal smem object,
which doesn't require PIN_MAPPABLE underneath in order to CPU map the
pages (unlike stolen). Extend i915_vma_pin_iomap() to directly use
i915_gem_object_pin_map() for such cases.
This change was suggested by Chris P Wilson, that we pin
the smem with i915_gem_object_pin_map_unlocked().
v2 (jheikkil): Change i915_gem_object_pin_map_unlocked to
i915_gem_object_pin_map
