isdn/bas_gigaset: use USB API functions rather than constants

himangi774 · davem330 · commit 14462b6e8c06 · 2014-08-22T12:23:10.000-07:00
This patch introduces the use of the function usb_endpoint_num.

The Coccinelle semantic patch that makes these changes is as follows:

@@ struct usb_endpoint_descriptor *epd; @@

- (epd-&gt;bEndpointAddress &amp; \(USB_ENDPOINT_NUMBER_MASK\|0x0f\))
+ usb_endpoint_num(epd)
