4.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: Xihan Zhang <[email protected]> commit 79b066bd76d501cfe8328142153da301f5ca11d1 upstream. This patch fixes a bug where sdma vm wasn't initialized when an sdma queue was created in HWS mode. This caused GPUVM faults to appear on dmesg and it is one of the causes that SDMA queues are not working.
