    ALSA: sound/usb: Use negated usb_endpoint_xfer_control, etc · 913ae5a2
    Julia Lawall authored
    This patch extends 42a6e66f by using
    usb_endpoint_xfer_control, usb_endpoint_xfer_isoc, usb_endpoint_xfer_bulk,
    and usb_endpoint_xfer_int in the negated case as well.
    
    This patch also rewrites some calls to usb_endpoint_dir_in as negated calls
    to !usb_endpoint_dir_out, and vice versa, to better correspond to the
    intent of the original code.
    
    The semantic patch that makes this change is as follows:
