If you receive any new drivers like the dt3155v4l that include
one of those files:
linux/videodev2.h
media/*.h
linux/dvb/*.h
They're dependent on the media core. So, could you please let me know about
its addition at staging, by either forwarding it to me or adding it at the
new staging/media c/c me on your reply?

At the current linux-next tree, the drivers are media stuff:
staging/easycap
staging/go7007
staging/solo6x10
staging/cx25821
staging/lirc
staging/cxd2099
staging/altera-stapl
staging/dt3155v4l
>From the above:
staging/tm6000 can be moved to /drivers/media/video, after a final checkpatch
cleanup patch I've made. However, I have some changesets for it on my -next tree,
so it is probably wiser if I move it on my tree instead on yours.
staging/cx25281 can also be moved to drivers/media/video after some codingstyle
fixups. I think you're received some such patches recently. Not sure if they cover the
remaining checkpatch.pl significative complains.
staging/cxd2099 has one problem: it exposes a wrong DVB API for the conditional
access module, due to the lack of a proper API definition. It is a driver optionally used
by some DVB cards, so moving it may require some include fixups. I don't want to move it
out of staging while we don't have a solution for the API issue. I'm planning to discuss
it during the media KS workshop in Plague.
staging/altera-stapl can be moved to drivers/misc. One include needs to be fixup
when moving it, as one DVB driver uses it for a couple boards that come with this
companion chipset.
If you prefer, I can do the git mv patches for those weird stuff.
