Hi
I am trying to load the cx23885 module. It fails to load and I get this in dmesg;
[ 433.506983] videobuf2_dma_sg: Unknown symbol dma_buf_export (err 0)
I wrote a small script to load each of the dependencies one at a time,
which shows pretty clearly the problem is videobuf2-dma-sg.ko.
I am up to date with the media_tree:
$ git log |head

v4l/compat.h: fix compiler warning
In file included from <command-line>:0:0:
v4l/compat.h:1605:11: warning: 'struct device_node' declared inside parameter list
u64 *out_values, size_t sz)
^
Can anyone point out how to fix this?
What other information would be useful?
Cheers
Vince
