[GoogleCodeExporter]

What steps will reproduce the problem?
1.running make in the comp;ile of the kernel
2.can't install module from the git clone - I keep getting 'invalid character' 
in module
3.

What is the expected output? see somagic.h
What do you see instead? nothing
if I try to complie the kernel the make command always crashed when it comes to 
the smi2012 section. This is the error I get:

What version of the product are you using? On what operating system?
easycap dc60 on fedora 16, I've also tried fedora 20, smae problem.

Please provide any additional information below.
I've been slogging at this for days, maybe this device is impossible install, I 
don't know. I can do all the steps at 
https://code.google.com/p/easycap-somagic-linux/wiki/GettingStarted
and device initialises as 1c88:003f but I cannot get /dev/video0 no matter 
what. If anyone has a step-by-step for fedora that would be good.

I'd encounter similar issue with kernel 3.16.3
kzalloc can be resolve by adding #include <linux/slab.h> at smi2021_main.c
while the s_std could be a v4l2 api changes?

manage to get it working with some patches smi2021_main.c, smi2021_v4l2.c

#1
change all:
    v4l2_device_call_all(&smi2021->v4l2_dev, 0, core, s_std,
to:
    v4l2_device_call_all(&smi2021->v4l2_dev, 0, video, s_std,
#2
change:
static int stop_streaming(struct vb2_queue *vq)
to:
static void stop_streaming(struct vb2_queue *vq)
*(and remove all return statements)

#3
change:
   smi2021->vb2q.timestamp_type = V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC;
to:
   smi2021->vb2q.timestamp_flags = V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC;

my kernel version is 3.16.3

update: kernel 3.16.6 patch smi2021_audio.c

change:
    rc = snd_card_create(SNDRV_DEFAULT_IDX1, "smi2021 Audio", THIS_MODULE,
                0, &card);
to:
    rc = snd_card_new(smi2021->dev, SNDRV_DEFAULT_IDX1, "smi2021 Audio", THIS_MODULE,
                0, &card);

Hi
When building with the 3.18.1 kernel (on openSUSE), there is also one more 
change in smi2021_v4l2.c

-   set_bit(V4L2_FL_USE_FH_PRIO, &smi2021->vdev.flags);
+   set_bit(V4L2_FL_USES_V4L2_FH, &smi2021->vdev.flags);

Attached, please find the full patch I used for openSUSE 13.2 and openSUSE 
Tumbleweed.
