KASAN catches it:\n\n\tslab-use-after-free in dma_chan_put+0x3e6/0x4c0\n\tRead of size 8 by task insmod/6319\n\tFreed by task 6319:\n\t  kfree+0x225/0x470\n\t  dma_chan_put+0x395/0x4c0\n\t  dmaengine_put+0xf8/0x160\n\nCache the module owner in dma_chan_put() before the put so the trailing\nmodule_put() does not need chan->device.",
