Xiaolei Wang 2838a89765 dmaengine: fsl-edma: Do not suspend and resume the masked dma channel when the system is sleeping 
Some channels may be masked. When the system is suspended,
if these masked channels are not filtered out, this will
lead to null pointer operations and system crash:

Unable to handle kernel NULL pointer dereference at virtual address
