From 9b2d99c0959e693e4dcea5f454bf84f229ca3d27 Mon Sep 17 00:00:00 2001

Subject: [PATCH] drm/v3d: Plug dma_fence leak
The irq_fence and done_fence are given a reference that is never
released. The necessary dma_fence_put()s seem to have been
deleted in error in an earlier commit.
Fixes: 0b73676836b2 ("drm/v3d: Clock V3D down when not in use.")
