From 134179823b3ca9c8b98e0631906459dbb022ff9b Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 29 Dec 2008 21:49:22 -0300 Subject: V4L/DVB (10130): 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_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/) // @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) // Signed-off-by: Julia Lawall Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/usbvideo/ibmcam.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/media/video/usbvideo/ibmcam.c') diff --git a/drivers/media/video/usbvideo/ibmcam.c b/drivers/media/video/usbvideo/ibmcam.c index c710bcd1df48..f8d85ddb4804 100644 --- a/drivers/media/video/usbvideo/ibmcam.c +++ b/drivers/media/video/usbvideo/ibmcam.c @@ -3779,11 +3779,11 @@ static int ibmcam_probe(struct usb_interface *intf, const struct usb_device_id * err("Alternate settings have different endpoint addresses!"); return -ENODEV; } - if ((endpoint->bmAttributes & 0x03) != 0x01) { + if (usb_endpoint_type(endpoint) != USB_ENDPOINT_XFER_ISOC) { err("Interface %d. has non-ISO endpoint!", ifnum); return -ENODEV; } - if ((endpoint->bEndpointAddress & 0x80) == 0) { + if (usb_endpoint_dir_out(endpoint)) { err("Interface %d. has ISO OUT endpoint!", ifnum); return -ENODEV; } -- cgit v1.2.3
