From db5e6df172309c382982790aafa8cd87dc0b6292 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 29 Dec 2008 11:19:10 +0100 Subject: USB: ub: use USB API functions rather than constants 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/) // @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) @inc@ @@ #include @depends on !inc && (r1||r5)@ @@ + #include #include // Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman --- drivers/block/ub.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) (limited to 'drivers') diff --git a/drivers/block/ub.c b/drivers/block/ub.c index 12fb816..b36b84f 100644 --- a/drivers/block/ub.c +++ b/drivers/block/ub.c @@ -2146,10 +2146,9 @@ static int ub_get_pipes(struct ub_dev *sc, struct usb_device *dev, ep = &altsetting->endpoint[i].desc; /* Is it a BULK endpoint? */ - if ((ep->bmAttributes & USB_ENDPOINT_XFERTYPE_MASK) - == USB_ENDPOINT_XFER_BULK) { + if (usb_endpoint_xfer_bulk(ep)) { /* BULK in or out? */ - if (ep->bEndpointAddress & USB_DIR_IN) { + if (usb_endpoint_dir_in(ep)) { if (ep_in == NULL) ep_in = ep; } else { @@ -2168,9 +2167,9 @@ static int ub_get_pipes(struct ub_dev *sc, struct usb_device *dev, sc->send_ctrl_pipe = usb_sndctrlpipe(dev, 0); sc->recv_ctrl_pipe = usb_rcvctrlpipe(dev, 0); sc->send_bulk_pipe = usb_sndbulkpipe(dev, - ep_out->bEndpointAddress & USB_ENDPOINT_NUMBER_MASK); + usb_endpoint_num(ep_out)); sc->recv_bulk_pipe = usb_rcvbulkpipe(dev, - ep_in->bEndpointAddress & USB_ENDPOINT_NUMBER_MASK); + usb_endpoint_num(ep_in)); return 0; } -- cgit v1.1
