From: Julia Lawall Date: Tue, 30 Dec 2008 00:49:22 +0000 (-0300) Subject: V4L/DVB (10130): use USB API functions rather than constants X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=134179823b3ca9c8b98e0631906459dbb022ff9b;p=openwrt%2Fstaging%2Fblogic.git 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;
