[PATCH v1] drm/msm: Move fence put to where failure occurs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If dma_fence_wait fails to wait for a supplied in-fence in
msm_ioctl_gem_submit, make sure we release that in-fence.

Also remove this dma_fence_put() from the 'out' label.
