From: Johan Hovold <johan@kernel.org> stable inclusion from linux-4.19.198 commit bfa8fce9c16596643939bacdf72fa6a4dc84a706 -------------------------------- commit 41e81022a04a0294c55cfa7e366bc14b9634c66e upstream. The direction of the pipe argument must match the request-type direction bit or control requests may fail depending on the host-controller-driver implementation. Fix the four control requests which erroneously used usb_rcvctrlpipe(). Fixes: 1d3e20236d7a ("[PATCH] USB: usbtouchscreen: unified USB touchscreen driver") Fixes: 24ced062a296 ("usbtouchscreen: add support for DMC TSC-10/25 devices") Fixes: 9e3b25837a20 ("Input: usbtouchscreen - add support for e2i touchscreen controller") Signed-off-by: Johan Hovold <johan@kernel.org> Cc: stable@vger.kernel.org # 2.6.17 Link: https://lore.kernel.org/r/20210524092048.4443-1-johan@kernel.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> --- drivers/input/touchscreen/usbtouchscreen.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/input/touchscreen/usbtouchscreen.c b/drivers/input/touchscreen/usbtouchscreen.c index d939c17985182..3f556af80bc56 100644 --- a/drivers/input/touchscreen/usbtouchscreen.c +++ b/drivers/input/touchscreen/usbtouchscreen.c @@ -264,7 +264,7 @@ static int e2i_init(struct usbtouch_usb *usbtouch) int ret; struct usb_device *udev = interface_to_usbdev(usbtouch->interface); - ret = usb_control_msg(udev, usb_rcvctrlpipe(udev, 0), + ret = usb_control_msg(udev, usb_sndctrlpipe(udev, 0), 0x01, 0x02, 0x0000, 0x0081, NULL, 0, USB_CTRL_SET_TIMEOUT); @@ -544,7 +544,7 @@ static int mtouch_init(struct usbtouch_usb *usbtouch) if (ret) return ret; - ret = usb_control_msg(udev, usb_rcvctrlpipe(udev, 0), + ret = usb_control_msg(udev, usb_sndctrlpipe(udev, 0), MTOUCHUSB_RESET, USB_DIR_OUT | USB_TYPE_VENDOR | USB_RECIP_DEVICE, 1, 0, NULL, 0, USB_CTRL_SET_TIMEOUT); @@ -556,7 +556,7 @@ static int mtouch_init(struct usbtouch_usb *usbtouch) msleep(150); for (i = 0; i < 3; i++) { - ret = usb_control_msg(udev, usb_rcvctrlpipe(udev, 0), + ret = usb_control_msg(udev, usb_sndctrlpipe(udev, 0), MTOUCHUSB_ASYNC_REPORT, USB_DIR_OUT | USB_TYPE_VENDOR | USB_RECIP_DEVICE, 1, 1, NULL, 0, USB_CTRL_SET_TIMEOUT); @@ -735,7 +735,7 @@ static int dmc_tsc10_init(struct usbtouch_usb *usbtouch) } /* start sending data */ - ret = usb_control_msg(dev, usb_rcvctrlpipe (dev, 0), + ret = usb_control_msg(dev, usb_sndctrlpipe(dev, 0), TSC10_CMD_DATA1, USB_DIR_OUT | USB_TYPE_VENDOR | USB_RECIP_DEVICE, 0, 0, NULL, 0, USB_CTRL_SET_TIMEOUT); -- 2.25.1
