From: Liam Howlett <liam.howlett@xxxxxxxxxx> Subject: drm/i915/selftests: use vma_lookup() in __igt_mmap() vma_lookup() will look up the vma at a specific address. find_vma() will start the search for a specific address and continue upwards. This fixes an issue with the selftest as the returned vma may not be the newly created vma, but simply the vma at a higher address.
