From: Julia Lawall <julia@xxxxxxx> 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 In drivers/net/wireless/zd1211rw/zd_usb.c the code: (endpoint->bEndpointAddress & USB_TYPE_MASK) == USB_DIR_OUT is suspicious. If it is intended to use USB_ENDPOINT_DIR_MASK rather than USB_TYPE_MASK, then the whole conditional test could be converted to a call to usb_endpoint_is_bulk_in. 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) @inc@ @@ #include <linux/usb.h> @depends on !inc && (r1||r5)@ @@ + #include <linux/usb.h> #include <linux/usb/...> // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/net/usb/hso.c | 2 +- drivers/net/wireless/zd1211rw/zd_usb.c | 3 +-- 2 files changed, 2 insertions(+), 3 deletions(-) diff --git a/drivers/net/usb/hso.c b/drivers/net/usb/hso.c index 2d41a10..6c30c4f 100644 --- a/drivers/net/usb/hso.c +++ b/drivers/net/usb/hso.c @@ -3177,7 +3177,7 @@ static struct usb_endpoint_descriptor *hso_get_ep(struct usb_interface *intf, for (i = 0; i < iface->desc.bNumEndpoints; i++) { endp = &iface->endpoint[i].desc; if (((endp->bEndpointAddress & USB_ENDPOINT_DIR_MASK) == dir) && - ((endp->bmAttributes & USB_ENDPOINT_XFERTYPE_MASK) == type)) + (usb_endpoint_type(endp) == type)) return endp; } diff --git a/drivers/net/wireless/zd1211rw/zd_usb.c b/drivers/net/wireless/zd1211rw/zd_usb.c index 04c1396..b5db57d 100644 --- a/drivers/net/wireless/zd1211rw/zd_usb.c +++ b/drivers/net/wireless/zd1211rw/zd_usb.c @@ -1065,8 +1065,7 @@ static int eject_installer(struct usb_interface *intf) /* Find bulk out endpoint */ endpoint = &iface_desc->endpoint[1].desc; if ((endpoint->bEndpointAddress & USB_TYPE_MASK) == USB_DIR_OUT && - (endpoint->bmAttributes & USB_ENDPOINT_XFERTYPE_MASK) == - USB_ENDPOINT_XFER_BULK) { + usb_endpoint_xfer_bulk(endpoint)) { bulk_out_ep = endpoint->bEndpointAddress; } else { dev_err(&udev->dev, -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
