device_control is an optional and not implemented in all DMA drivers. Any calls to these will result in a NULL pointer dereference. dmatest makes two of these calls when completing the kernel thread and removing the module. These are corrected by calling the dmaengine_device_control wrapper and checking for a non-existant device_control function pointer there.
