Can be taken immediately. Patch v4 2/5: Looks good, not useful as standalone patch, can be taken with rest of series. Patch v4 3/5: I need to revisit this and look at new dma pool lifetime vs xHC accessing those DMA addresses. PAtch v4 Rest: ALSA, no opinion. > > But, I think your suggestion about adding the sideband check in the xhci_setup_device() would mitigate that problem.  Esp, if we don't want xHCI core to really know about sideband ops. That would be the bandaid in: https://lore.kernel.org/all/c6c9890f-46d8-42f1-a7e7-8a5d551fa22c@linux.intel.com/ I can turn that into a proper patch. Lianqin also gave some preliminary positive feedback, but I'm not sure if the code was ever properly tested. Thanks Mathias
