[igt-dev] [PATCH i-g-t v3 47/52] tests/kms_flip: Adopt to use allocator

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

From: Bhanuprakash Modem <bhanuprakash.modem@intel.com>

For newer gens kernel will reject relocations returning -EINVAL
so we should just provide the allocator handle to inject the hang.
