SubjectRe: [RFC 2/3] USB: core: Add non-coherent buffer allocation helpers
Please don't introduce new DMA_ATTR_NON_CONSISTENT users, it is
a rather horrible interface, and I plan to kill it off rather sooner
than later. I plan to post some patches for a better interface
that can reuse the normal dma_sync_single_* interfaces for ownership
transfers. I can happily include usb in that initial patch set based
on your work here if that helps.
