Subject: [PATCH] mei: dma: silent the reject message
|
|
|
|
Not all FW versions support DMA on their first release,
|
|
hence it is normal behavior to receive a reject response
|
|
upon DMA setup request.
|
|
In order to prevent confusion, the DMA setup reject message
|
|
is printed only in debug level.
|
