The struct prototype is defined at the beginning of the code as
"si2157_ops" but the real struct is called "si2157_tuner_ops".
This is causing the name to be empty on this info msg: si2157 16-0060:

Some drivers, like au0828 are very sensitive to tuner sleep and may
break if the sleep happens too fast. Also, by keeping the tuner alive
for a while could speedup tuning process during channel scan. So,
change the logic to delay the actual sleep to 5 seconds after its
command.

That tuner driver is mainly for DVB API, but there is some V4L2 API
controls for SDR usage. Make driver compile conditional so that V4L2
is not mandatory. Without the V4L2 support driver is build as a DVB

Used synthesizer is very typical integer-N PLL, with configurable
reference frequency divider, output frequency divider and of
course N itself. Most common method to calculate values is first
select output divider, then calculate VCO frequency and finally
calculate PLL N from VCO frequency. Do it that way.
Also make some cleanups for filter logic and signal strength.

Pull media build fixes from Mauro Carvalho Chehab:
"A series of patches that fix compilation on non-x86 archs.
While most of them are just build fixes, there are some fixes for real
bugs, as there are a number of drivers using dynamic stack allocation.
A few of those might be considered a security risk, if the i2c-dev
module is loaded, as someone could be sending very long I2C data that
could potentially overflow the Kernel stack. Ok, as using /dev/i2c-*
devnodes usually requires root on usual distros, and exploiting it
would require a DVB board or USB stick, the risk is not high"

- some improvements on buffer allocation at VB2 core

PS this time, we have a smaller number of patches. While it is hard
to pinpoint to the reasons, I believe that it is mainly due to:
1) there are several patch series ready, but depending on DT review.
I decided to grant some extra time for DT maintainers to look on
it, as they're expecting to have more time with the changes agreed
during ARM mini-summit and KS. If they can't review in time for
3.14, I'll review myself and apply for the next merge window.

Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
drivers/media/tuners/tuner-xc2028.c:651:1: warning: 'load_firmware' uses dynamic stack allocation [enabled by default]
Instead, let's enforce a limit for the buffer.
In the specific case of this driver, the maximum limit is 80, used only
on tm6000 driver. This limit is due to the size of the USB control URBs.
Ok, it would be theoretically possible to use a bigger size on PCI
devices, but the firmware load time is already good enough. Anyway,
if some usage requires more, it is just a matter of also increasing
the buffer size at load_firmware().

Instead, let's enforce a limit for the buffer. Considering that I2C
transfers are generally limited, and that devices used on USB has a
max data length of 64 bytes for the control URBs.
So, it seem safe to use 64 bytes as the hard limit for all those devices.
On most cases, the limit is a way lower than that, but this limit
is small enough to not affect the Kernel stack, and it is a no brain
limit, as using smaller ones would require to either carefully each
driver or to take a look on each datasheet.
