From 134179823b3ca9c8b98e0631906459dbb022ff9b Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 29 Dec 2008 21:49:22 -0300 Subject: [PATCH] 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;
