If that work is\ncancelled that reference is leaked. Since\ncommit f5cc545f5969 (\"thunderbolt: Wait for tb_domain_release() to\ncomplete when driver is removed\") instead of just leaking memory this\nnow also blocks in the completion wait forever when unbinding the\ndriver.\n\nThis can be triggered whenever a DP tunnel is torn down before the DPRX\nread has completed, e.g. by unplugging within the timeout, and then\nunbinding the driver.\n\nThat reference only exists to keep the domain around while the DPRX work\nis scheduled so let the work itself own it: take it in tb_dp_dprx_start()\nand drop it in both places that end the work. Get/put are then paired\ninside the same file and it doesn\u0027t matter anymore if the callback ever\nruns."
