which is then used in an async call. That memory isn't freed in the callback though the control request and URB are. The easy fix is to just free the urb->transfer_buffer which would be ok for now, but that seems like a tacky thing to do with ax8817x_write_async_cmd since there could be future invocations where I'm not using a temporary buffer that should be freed after the call. Any suggestions on a clean way to free that memory?
Maybe there should be a few driver-defined bits in urb->transfer_flags, to help distinguish such cases? We have plenty of unused ones.
