Hi, this patch should fix everything you complained about. As I don't have the hardware, please test.
I don't have the hardware either so can't help you there.
static void usbtouch_close(struct input_dev *input)
{
struct usbtouch_usb *usbtouch = input_get_drvdata(input);
+ mutex_lock(&usbtouch->lock);
+ usbtouch->open = 0;
+ mutex_unlock(&usbtouch->lock);
usb_kill_urb(usbtouch->irq);usb_kill_urb() is still not protected by the mutex but a resume happening here wouldn't resubmit the urb so I suppose it's OK to leave it like that. -- Ville Syrjälä syrjala@sci.fi http://www.sci.fi/~syrjala/ -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
