No. You'll need to clone the entire kernel tree (either Linus one or
mine).
The build system at the Kernel will rebuild an entire Kernel image.
You'll then need to boot that new image.
That takes some machine time, but, after the first compilation, the
subsequent compilations are faster.
I recommend you to use a minimal .config file for the compilation,
as this speeds up a lot the time to compile the Kernel.
Here, I use this small script to produce such mini-kernel:
http://ftp.suse.com/pub/people/tiwai/misc/diet-kconfig
After running it (and using the default for whatever question it
asks me), I do a make menuconfig, to be sure that the media
drivers and options I want are there.
In summary, what I suggest is:
$ git clone
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
$ git checkout v3.2
$ git bisect good
$ diet-kconfig
$ make menuconfig
select what is missed at media stuff
$ make && make modules install && make install & reboot
after reboot check if everything is ok
$ git bisect bad v3.4
repeat:
$ make && make modules install && make install & reboot
it will likely ask you about some new drivers = it is generally safe
to just let the default - just be more careful with the media
menuconfig items
test the kernel:
if OK:
$ git bisect good
if BAD:
$ git bisect bad
if git bisect answers that there are xxx bisects left, then goto repeat
After running the above, git bisect will put its fingers on the broken patch.

[media] cx23885-dvb: Remove a dirty hack that would require DVBv3
The cx23885-dvb driver has a dirty hack:
1) it hooks the DVBv3 legacy call to FE_SET_FRONTEND;
2) it uses internally the DVBv3 struct to decide some
configs.
Replace it by a change during the gate control. This will
likely work, but requires testing. Anyway, the current way
will break, as soon as we stop copying data for DVBv3 for
pure DVBv5 calls.
Compile-tested only.

I manually removed the patch, then the TV card works.
Unfortunately my lack of knowledge prevents me fix it.
I test new code with pleasure :) !
Thanks,
