From patchwork Mon Dec 29 10:20:42 2008 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: [5/13] drivers/mtd/nand: use USB API functions rather than constants Date: Mon, 29 Dec 2008 00:20:42 -0000 From: Julia Lawall X-Patchwork-Id: 15893 Message-Id: To: dwmw2@infradead.org, linux-mtd@lists.infradead.org, gregkh@suse.de, linux-kernel@vger.kernel.org, kernel-janitors@vger.kernel.org From: Julia Lawall 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 --- drivers/mtd/nand/alauda.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/mtd/nand/alauda.c b/drivers/mtd/nand/alauda.c index 9623803..6d96491 100644 --- a/drivers/mtd/nand/alauda.c +++ b/drivers/mtd/nand/alauda.c @@ -676,11 +676,11 @@ static int alauda_probe(struct usb_interface *interface, goto error; al->write_out = usb_sndbulkpipe(al->dev, - ep_wr->bEndpointAddress & USB_ENDPOINT_NUMBER_MASK); + usb_endpoint_num(ep_wr)); al->bulk_in = usb_rcvbulkpipe(al->dev, - ep_in->bEndpointAddress & USB_ENDPOINT_NUMBER_MASK); + usb_endpoint_num(ep_in)); al->bulk_out = usb_sndbulkpipe(al->dev, - ep_out->bEndpointAddress & USB_ENDPOINT_NUMBER_MASK); + usb_endpoint_num(ep_out)); /* second device is identical up to now */ memcpy(al+1, al, sizeof(*al));
