Description
In the Linux kernel, the following vulnerability has been resolved:

dmaengine: Fix possible use after free

In dma_release_channel(), check chan->device->privatecnt after call
dma_chan_put(). However, dma_chan_put() call dma_device_put() which could
release the last reference of the device if the DMA provider is already
gone and hence free it.

Fixes it by moving dma_chan_put() after the check.
