Subject[PATCH v3 03/12] dmaengine: at_xdmac: Print debug message after realeasing the lock
Date
It is desirable to do the prints without the lock held if possible, so
move the print after the lock is released.

Fixes: e1f7c9eee707 ("dmaengine: at_xdmac: creation of the atmel eXtended DMA Controller driver")
