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_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)
