V4L/DVB (7188): radio-si470x version 1.0.6
This patch combines all the finished discussions and its resulting patches from
the mailing list.
The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of
small issues, that are fixed with this patch now. For me the most interesting
thing is, that it's now safer to use it on other architectures.
The history for version 1.0.6 is:
- fixed coverity checker warnings in *_usb_driver_disconnect
- probe()/open() race by correct ordering in probe()
- DMA coherency rules by separate allocation of all buffers
- use of endianness macros
- abuse of spinlock, replaced by mutex
- racy handling of timer in disconnect, replaced by delayed_work
- racy interruptible_sleep_on(), replaced with wait_event_interruptible()
- handle signals in read()
The driver is tested with all Debian/testing radio programs and rdsd. The patch
is tested against checkpatch.pl v1.12.

So, only one board could use an USB host at the same time. After the patch, it
is possible to use more than one em28xx at the same time, on the same usb host,
if the image size is slower or equal to 345600, since those images will
require about 30% of the URBs:

V4L/DVB (7091): radio-si470x improvements and seldom problem fixed in tuning functions
I updated the radio-si470x driver another time. Here are the commented history entries:
- number of seek_retries changed to tune_timeout
The last versions checked for the end of frequency tuning by polling a si470x register.
Therefore polling depended on the usb utilization.
This was changed to have a constant timeout now.
- fixed problem with incomplete tune operations by own buffers
The last version used a shared buffer to assembly the USB HID reports.
It sometimes happened, that multiple functions were modifing this buffer simultanuously.
When sending such reports, the hardware returned USB stalls (-EPIPE).
Now buffers of the correct size (smaller than before) are allocated as local variables.
- optimization of variables
The size of some variables has been reduced to allow the compiler to generate more optimized code.
- improved error logging
At some important location, error checking was improved.
Especially the usb transfers to access si470x registers and the tuning functions were modified.

V4L/DVB (7084): saa7134: add support for the Medion / Creatix CTX948 card
This adds support for analog inputs and DVB-T.
Good sensitivity for DVB-T currently needs to use analog TV first.
DVB-S support is not yet completed, but is on the way.
As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.
This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.
After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.
This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.
