Subject: [PATCH] drm/i915: Wake device for emitting request during selftest
Git-commit: 10e9bd9ab0322a3929db0bf84ff1ca3f28ed0ee4
Patch-mainline: v4.13-rc1
References: FATE#322643 bsc#1055900

igt_mmap_offset_exhaustion() selftest was using live requests to make an
object busy, but we did not hold a runtime pm wakeref for submitting the
requests. Acquire it to avoid triggering "RPM wakelock ref not held
during HW access" warnings.
