[media] si2168: add support for firmware files in new format
This patch adds support for new type of firmware versions of Si2168 chip.
Old type: n x 8 bytes (all data, first byte seems to be 04 or 05)
New type: n x 17 bytes (1 byte indicates len and max 16 bytes data)
New version of TechnoTrend CT2-4400 drivers
(http://www.tt-downloads.de/bda-treiber_4.3.0.0.zip) contains newer
firmware for Si2168-B40 that is in the new format. It can be extracted
with the following command:

[media] stv090x: remove export symbol for stv090x_set_gpio()
Drivers that use dvb_attach can have just one exported symbol,
or they will cause compilation breakages depending on the
selected frontends.
As Jim reported:
drivers/built-in.o: In function `technisat_usb2_set_voltage':
technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio'
make: *** [vmlinux] Error 1
That happens because, on his configuration, the configuration
is:
CONFIG_DVB_USB=y
CONFIG_DVB_STV090x=m
Luis proposed ar way to fix, but that would just force the
STV090x to be selected, even if one wants to use a device
with a different frontend.
Instead, let's do the right thing: move set_gpio to the
configuration structure and fill it during dvb_attach().
This way, the driver can still call it, and dvb_attach()
will load stv090x module only if the device really needs it.

This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put

prepare/finish memops.
Now that vb2-dma-sg will sync the buffers for you in the prepare/finish
memops we can drop that from the drivers that use dma-sg.
For the solo6x10 driver that was a bit more involved because it needs to
copy JPEG or MPEG headers to the buffer before returning it to userspace,
and that cannot be done in the old place since the buffer there is still
setup for DMA access, not for CPU access. However, the buf_finish
op is the ideal place to do this. By the time buf_finish is called
the buffer is available for CPU access, so copying to the buffer is fine.

[media] v4l2: get/set prio using video_dev prio structure
The v4l2_device structure embed a v4l2_prio_state structure used by
default for priority handling, but drivers can override that default by
setting the video_dev prio pointer to a different v4l2_prio_state
instance.
However, the VIDIO_G_PRIORITY and VIDIOC_S_PRIORITY implementations use
the prio state embedded in v4l2_device unconditionally, breaking drivers
that need to override the default. Fix them.

The cause is that uvc_status_cleanup() is called after usb_put_*() in
uvc_delete(). usb_put_*() removes the sysfs parent and eventually
removes the children recursively, so the later device_del() can't find
its sysfs. The fix is simply rearrange the call orders in
uvc_delete() so that the child is removed before the parent.

Never use sg++, always use sg = sg_next(sg). Scatterlist entries can

As far as I can tell cx88 and ivtv are really broken because of this,
and bttv and cx25821 are OK because vb1 doesn't combine scatterlist
entries.
But regardless, sg++ should never be used, only sg_next is safe.
