[PATCH 4.19 229/239] dmaengine: at_xdmac: Print debug message after realeasing the lock

[Greg Kroah-Hartman]

From: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx>

commit 5edc24ac876a928f36f407a0fcdb33b94a3a210f upstream.

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")
