Hello.
i was testing media_build on a test vm with one of my usb dvb-t2 devices.
a few weeks ago this worked fine and modules loaded but now during boot
i get the below errors in dmesg.
any idea whats going on?
can someone also tell me how to go back to an earlier version or point
me to where i can do some reading about it so i can try to find out when
it broke?

managed to bisect this and found the commit from where it broke.
this one does not work:
0d3ab84 [media] dvb core: must check dvb_create_media_graph()
but the commit just before do work:
13f6e88 [media] v4l2 core: enable all interface links at init
unfortunately i know too little of the code to understand why it broke.
while doing this i learned several other things, like it is not fun to
try to bisect thru the non media changes (kernel update i think).
and in media_build backports/api_version.patch tends to not apply
cleanly sometimes so had to go back to media_build commit 2679653 to do
the testing.
