af9035 vs. it913x

Hello,

old it913x had support reporting of signal strength on IT9135 v2. af9035 driver does not. Could that be corrected ?

And I would like to know:
How to get and build drivers from source with patches which are presented in this forum.

E.g. - driver it913x is now obsolete and IT9135 is now moved to driver af9035. OK. But when I download:

git clone --depth=1 git://linuxtv.org/media_build.git

as described here:
http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

There are these changes/patches not included.
Is somewhere more actual media_build.git to clone an build ?

Thanks
