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.")
