Pixel Ding c4760b9c8d drm/amdgpu: bypass lru touch for KIQ ring submission
[ Upstream commit dce1e131dd ]

KIQ ring submission is used for register accessing on SRIOV
VF that could happen both in irq enabled and irq disabled cases.
Inversion lock could happen on adev->ring_lru_list_lock, while
this operation is useless and just adds overhead in this use
case.
