/**
The direction field of the ipa_cmd_info structure is set, but never used. It seems it might have been used for the DMA_SHARED_MEM immediate command, but the DIRECTION flag is set based on the value of the passed-in direction flag there. Anyway, remove this unused field from the ipa_cmd_info structure. This is done as a separate patch to make it very obvious that it's not required.
