ALSA: sound/usb: Use negated usb_endpoint_xfer_control, etc
This patch extends 42a6e66f1e40a930d093c33ba0bb9d8d8e4555ed by using usb_endpoint_xfer_control, usb_endpoint_xfer_isoc, usb_endpoint_xfer_bulk, and usb_endpoint_xfer_int in the negated case as well. This patch also rewrites some calls to usb_endpoint_dir_in as negated calls to !usb_endpoint_dir_out, and vice versa, to better correspond to the intent of the original code. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_CONTROL\|0\)) + !usb_endpoint_xfer_control(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_ISOC\|1\)) + !usb_endpoint_xfer_isoc(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_BULK\|2\)) + !usb_endpoint_xfer_bulk(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_INT\|3\)) + !usb_endpoint_xfer_int(epd) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Takashi Iwai <tiwai@suse.de>
