V4L/DVB (7712): pvrusb2: Close connect/disconnect race
If a disconnect happens before initialization is completed, the

inside that lock, the initialization function should abort if it is
discovered that a disconnect has already taken place.

V4L/DVB (7711): pvrusb2: Fix race on module unload
The pvrusb2 driver - for basically forever - was not enforcing a
proper module tear-down. Kernel threads are used inside the driver
and all must be gone before the module can be safely removed. This
changeset reimplements a chunk of pvrusb2-context.c to enforce this
correctly. Unfortunately this is not a simple fix. The new
implementation also cuts back on kernel thread usage; instead of there
being 1 control thread per instance now it's just 1 control thread
shared by all instances. (By dropping to a single thread then the
module exit function can block on its shutdown and the thread itself
can monitor and cleanly shut down all of the other instances first.)

Basically it resets read and write pointers to 0 in case they are
beyond the new size of the buffer.

V4L/DVB (7654): tda10086: make the xtal frequency a configuration option
Some DVB-S boards, i.e. with the SD1878 tuner, use a 4 MHz reference frequency.
This reqires a different setup of the clock PLL.
This patch adds an enum to the tda10086_config struct and sets the proper
values for the boards.
This patch also fixes the DVB-S section of the MD7134_BRIDGE_2

V4L/DVB (7651): tuner-xc2028: Several fixes to SCODE
This patch fixes several issues on SCODE:
1) The extracting tool weren't generating the proper tags for SCODE. This
has almost no effect, since those tags shouldn't be used;
2) DIBCOM52 were using a wrong IF. It should be 5200, instead of 5700;
3) seek_firmware were wanting an exact match for firmware type. This is
wrong. As result, no SCODE firmware were loaded;
4) A few files were including the wrong file for seeking demod firmwares;
5) XC3028_FE_DEFAULT can be used, if user doesn't want to load a firmware.
However, this weren't documentated. This feature require more testing.
