Subject: [PATCH] dmaengine: tegra: Fix memory leak in terminate_all()
Git-commit: a7a7ee6f5a019ad72852c001abbce50d35e992f2
Patch-mainline: v6.2-rc5
References: git-fixes
Terminate vdesc when terminating an ongoing transfer.
This will ensure that the vdesc is present in the desc_terminated list
The descriptor will be freed later in desc_free_list().
This fixes the memory leaks which can happen when terminating an
ongoing transfer.
