From 96bcd090fa434b4369e6e3a9cba937d1e513596d Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 24 Jan 2009 17:57:24 -0800 Subject: USB: musb uses endpoint functions 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_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) @inc@ @@ #include @depends on !inc && (r1||r5)@ @@ + #include #include // Signed-off-by: Julia Lawall Acked-by: Felipe Balbi Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman --- drivers/usb/musb/musb_gadget.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'drivers/usb/musb/musb_gadget.c') diff --git a/drivers/usb/musb/musb_gadget.c b/drivers/usb/musb/musb_gadget.c index 6197daeab8f9..4ea305387981 100644 --- a/drivers/usb/musb/musb_gadget.c +++ b/drivers/usb/musb/musb_gadget.c @@ -874,10 +874,10 @@ static int musb_gadget_enable(struct usb_ep *ep, status = -EBUSY; goto fail; } - musb_ep->type = desc->bmAttributes & USB_ENDPOINT_XFERTYPE_MASK; + musb_ep->type = usb_endpoint_type(desc); /* check direction and (later) maxpacket size against endpoint */ - if ((desc->bEndpointAddress & USB_ENDPOINT_NUMBER_MASK) != epnum) + if (usb_endpoint_num(desc) != epnum) goto fail; /* REVISIT this rules out high bandwidth periodic transfers */ @@ -890,7 +890,7 @@ static int musb_gadget_enable(struct usb_ep *ep, * packet size (or fail), set the mode, clear the fifo */ musb_ep_select(mbase, epnum); - if (desc->bEndpointAddress & USB_DIR_IN) { + if (usb_endpoint_dir_in(desc)) { u16 int_txe = musb_readw(mbase, MUSB_INTRTXE); if (hw_ep->is_shared_fifo) -- cgit v1.2.3
