commit 3a5fd0dbd87853f8bd2ea275a5b3b41d6686e761 upstream.
Commit b53611fb1ce9 ("dmaengine: tegra210-adma: Fix crash during probe") has moved some code in the probe function and reordered the error handling path accordingly. However, a goto has been missed.
Fix it and goto the right label if 'dma_async_device_register()' fails, so that all resources are released.
