Good point. In fact IIRC we've always had the policy that drivers should do their best to generate aligned packets but it is not a requirement since on some platforms it's more important for the DMA to be aligned. So it's up the platform code to fix up any exceptions should they show up. Daniel, what's the specific case that you had in mind with this patch?
