-If dma_async_device_register() returns error and probe should clean up
-and return error, a NULL pointer exception happens because of
-dereference of not allocated channel thread:
-
-Dmesg log (from early printk):

-Subject: dmaengine: pl330: Fix NULL pointer dereference on probe failure
-
-From: Krzysztof Kozlowski <k.kozlowski@samsung.com>
-
-commit 0f5ebabdd03b471da1906f7edddc61ceb35cee02 upstream.
-
-If dma_async_device_register() returns error and probe should clean up
-and return error, a NULL pointer exception happens because of
-dereference of not allocated channel thread:
-
-Dmesg log (from early printk):
