[media] ds3000: bail out early on i2c failures during firmware load
- if kmalloc() returns NULL, we can return immediately without trying
to kfree() a NULL pointer.
- if i2c_transfer() fails, error out immediately instead of trying to
upload the remaining bytes of the firmware.
- the error code is then properly propagated down to ds3000_initfe().

[media] dvb: push down ioctl lock in dvb_usercopy
Since most dvb ioctls wrap their real work with dvb_usercopy, the static mutex
used in dvb_usercopy effectively is a global lock for dvb ioctls.
Unfortunately, frontend ioctls can be blocked by the frontend thread for
several seconds; this leads to unacceptable lock contention. Mitigate that by
pushing the mutex from dvb_usercopy down to the individual, device specific
ioctls.
There are 10 such ioctl functions using dvb_usercopy, either calling it
directly, or via the trivial wrapper dvb_generic_ioctl. The following already
employ their own locking and look safe:
• dvb_demux_ioctl (as per dvb_demux_do_ioctl)
• dvb_dvr_ioctl (as per dvb_dvr_do_ioctl)
• dvb_osd_ioctl (as per single non-trivial callee)
• fdtv_ca_ioctl (as per callees)
• dvb_frontend_ioctl
The following functions do not, and are thus changed to use a device specific
mutex:
• dvb_net_ioctl (as per dvb_net_do_ioctl)
• dvb_ca_en50221_io_ioctl (as per dvb_ca_en50221_io_do_ioctl)
• dvb_video_ioctl

I was testing my video-over-ethernet subsystem recently, and vivi
seemed to be perfect video source for testing when one don't have lots
of capture boards and cameras. Only its framerate was hardcoded to
NTSC's 30fps, while in my country we usually use PAL (25 fps) and I
needed that to precisely simulate bandwidth.
That's why here is this patch with ->enum_frameintervals() and
->{g,s}_parm() implemented as suggested by Hans Verkuil which passes
v4l2-compliance and manual testing through v4l2-ctl -P / -p <fps>.
Regarding newly introduced __get_format(u32 pixelformat) I decided not
to convert original get_format() to operate on fourcc codes, since >= 3
places in driver need to deal with v4l2_format and otherwise it won't be
handy.

Tested with Silvercrest 1.3 Mpixel webcam (em2710) on both bulk and isoc
modes.
Tested analog with HVR-950 model 65201/A1C0 (em2883), where only ISOC
endpoints are available for both DVB and Analog.
Tested on Hauppauge WinTV USB 2 (em2840) on both bulk and isoc modes.
It should be noticed that enabling bulk mode by default with TV boards
is a bad idea; what happens is that, while with ISOC the USB logic will
prevent the concurrent usage of two devices that spends more than 100%
of the USB2 traffic, it doesn't care with bulk transfers.
On my tests, I started two streams, one with a WinTV at 640x480x30fps
and the other one with a Silvercrest webcam at 640x480, on a lower fps)
both on bulk mode. One of the streams always silently failed.

[media] em28xx: move the em2710/em2750/em28xx specific frame data processing code to a separate function
em28xx_urb_data_copy() actually consists of two parts:
USB urb processing (checks, data extraction) and frame data packet processing.
Move the latter to a separate function and call it from em28xx_urb_data_copy()
for each data packet.
The em25xx, em2760, em2765 (and likely em277x) chip variants are using a
different frame data format, for which support will be added later with
another function.
This reduces the size of em28xx_urb_data_copy() and makes the code much more
readable. While we're at it, clean up the code a bit (rename some variables to
something more meaningful, improve some comments etc.)

[media] em28xx: move caching of pointer to vmalloc memory in videobuf to struct em28xx_buffer
In the current code em28xx_urb_data_copy() caches the pointer to the vmalloc
memory in videobuf locally.
The alternative would be to call videobuf_to_vmalloc() for each processed USB
data packet (isoc USB transfers => 64 times per URB) in the em28xx_copy_*()
functions.
With the next commits, the data processing code will be split into functions
for serveral reasons:
- em28xx_urb_data_copy() is generally way to long, making it less readable
- there is code duplication between VBI and video data processing
- support for em25xx data processing (uses a different header and frame
end signaling mechanism) will be added
This would require extensive usage of pointer-pointers, which usually makes the
code less readable and prone to bugs.
The better solution is to cache the pointer in struct em28xx_buffer.
This also improves consistency, because we already track the buffer fill count there.

[media] em28xx: refactor VBI data processing code in em28xx_urb_data_copy()
When a new frame header is detected in em28xx_urb_data_copy() and the data
packet contains both, VBI data and video data, the prevoius VBI buffer doesn't
get finished and is overwritten with the new VBI data.
This bug is not triggered with isochronous USB transfers, because the data
packetes are much smaller than the VBI data size.
But when using USB bulk transfers, the whole data of an URB is treated as
single packet, which is usually much larger then the VBI data size.
Refactor the VBI data processing code to fix this bug, but also to simplify the
code and make it similar to the video data processing code part (which allows
further code abstraction/unification in the future).
The changes have been tested with device "Hauppauge HVR-900".
