dmaengine: core: Revert back to pr_debug in __dma_request_channel()
Commit ef859312c3a1 ("dmaengine: core: Use dev_ functions for debug and
error prints") wasn't quite right in __dma_request_channel() by claiming
that all pr_ prints have valid DMA channel pointer. Obviously it is not
true as __dma_request_channel() is looking for a channel and returns NULL
if it does not find it.
Prevent this potential NULL pointer dereference by reverting back to
pr_debug().
