Droidcam - v4l2loopback-dc module won't compile with current kernels

[H0wdy]

I use droidcam to use my phone as a camera/webcam. After 3.17, though, it won't compile the module anymore, generating this error:

any ideas?

Hi,

vidioc_s_std() definition have changed from

static int vidioc_s_std (struct file *file,  void *private_data,  v4l2_std_id *_std)

to

static int vidioc_s_std (struct file *file,  void *private_data,  v4l2_std_id _std)

you have to modify references to _std from

 if(_std) {
    req_std=*_std;
    *_std=all_std;
  }

to

if(_std) {
    req_std=_std;
  }

and both vidioc_s_audout() and vidioc_s_audio just need "const struct v4l2_audio *arg"
but this doesn't really care as arguments are not used

sorry, I was not able to attach the patch.. upload fail, and my old account disappear
