The two functions are mostly identical. They handle the copy_from_user
and copy_to_user operations related with V4L2 ioctls and call the real
ioctl handler.

Create a __video_usercopy function that implements the core of
video_usercopy and video_ioctl2, and call that function from both.

one uses a mutex, one uses the BKL and one does

so let's make all of them use the same mutex,
and get rid of one more BKL user.

This is the core of the WL1273 FM radio driver, it connects
the two child modules. The two child drivers are
drivers/media/radio/radio-wl1273.c and sound/soc/codecs/wl1273.c.

The radio-wl1273 driver implements the V4L2 interface and communicates
with the device. The ALSA codec offers digital audio, without it only
analog audio is available.

kmalloc() can fail so check whether state->internal is NULL.
append_internal() can return NULL on allocation failures so check that.
Also if we hit the error condition later in the function then there is
a memory leak and we need to call remove_dev() to fix it.

Also Oliver Endriss pointed out an additional leak that I missed in the
first version of this patch.

get_user_pages() may return -errno, such as -EFAULT.  So don't blindly use
its return value as an offset into dma->map[] for the next get_user_pages()
call.  Since we'll give up and return an error if either fails, don't even
make the second call if the first failed to give us exactly what we were
looking for.

The old code would also call put_page() on as many elements of dma->map[]
as we'd asked for, regardless of how many were valid.

[Andy Walls modified this patch to return -EFAULT instead of -EINVAL
as Paul's observation "I'm not sure -EINVAL is the best return code vs
-EFAULT or -ENOMEM, [...]" was correct.  The return value bubbles up
as a return code for write(), for which the V4L2 API spec indicates
EINVAL is incorrect and EFAULT is correct.]
