I just pushed the pending patched and added a reverted patch for
b89193e0b06f at the media_tree.git. Could you please use it to compile
or, if you prefer to keep using 3.16, you can use the media_build.git[1]
tree to just use the newest media stack on the top of 3.16.

I updated the today's tarball for it to have all the patches there.

Please check if the xc5000 issue disappears with the current patches.

The drxk issue will likely need a similar fix to the one that Shuah
did to drxj.

Shuah,

Could you please take a look at the drx-k driver? It is not that different
from the drx-j.

Regards,
Mauro
