Subject: [PATCH 14/52] drm/i915: Permit pinning whilst the device is 'suspended'
From: Chris Wilson <chris@...is-wilson.co.uk>
commit e3d8affb0d2d95f2da61e30ce86b33177feb91e8 upstream.
As pinning (allocating and binding GTT memory) does not actually invoke
GPU commands, it is safe, and indeed is attempted, during resumption
from suspension:
[drm:intel_init_clock_gating] *ERROR* failed to pin power context: -16
