Now applied with an amended commit message:

    USB: serial: kl5kusb105: use usb_control_msg_recv() and usb_control_msg_send()
    
    The wrappers usb_control_msg_send/recv eliminate the need of
    manually allocating DMA buffers for USB messages. They also treat
    short reads as an error. Hence use the wrappers and remove DMA
    allocations.
    
    Note that short reads are now logged as -EREMOTEIO instead of the amount
    of data read.

I've applied all but the first two patches in the series now. Would you
mind respinning those two?

Thanks,
Johan
