    V4L/DVB (10130): use USB API functions rather than constants · 13417982
    Julia Lawall authored
    This set of patches introduces calls to the following set of functions:
    
    usb_endpoint_dir_in(epd)
    usb_endpoint_dir_out(epd)
    usb_endpoint_is_bulk_in(epd)
    usb_endpoint_is_bulk_out(epd)
    usb_endpoint_is_int_in(epd)
    usb_endpoint_is_int_out(epd)
    usb_endpoint_is_isoc_in(epd)
    usb_endpoint_is_isoc_out(epd)
    usb_endpoint_num(epd)
    usb_endpoint_type(epd)
    usb_endpoint_xfer_bulk(epd)
    usb_endpoint_xfer_control(epd)
    usb_endpoint_xfer_int(epd)
    usb_endpoint_xfer_isoc(epd)
    
    In some cases, introducing one of these functions is not possible, and it
    just replaces an explicit integer value by one of the following constants:
    
    USB_ENDPOINT_XFER_BULK
    USB_ENDPOINT_XFER_CONTROL
    USB_ENDPOINT_XFER_INT
    USB_ENDPOINT_XFER_ISOC
    
    An extract of the semantic patch that makes these changes is as follows:
    (http://www.emn.fr/x-info/coccinelle/)
    
    // <smpl>
    @r1@ struct usb_endpoint_descriptor *epd; @@
    
    - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) ==
    - \(USB_ENDPOINT_XFER_CONTROL\|0\))
    + usb_endpoint_xfer_control(epd)
    
    @r5@ struct usb_endpoint_descriptor *epd; @@
    
    - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) ==
    -  \(USB_DIR_IN\|0x80\))
    + usb_endpoint_dir_in(epd)
    // </smpl>
