Re: 2.6.24-rc5 "videobuf_read_start" [drivers/media/video/videobuf-dvb.ko] undefined!

[Adrian Bunk <bunk@kernel.org>]

Patch looks good, it seems a merge conflict of
commit 19bc5133dae9562e8824ef101464061f9854c1d8
was resolved the wrong way.

@Mauro:
Any objections against a later path that changes the exports to the 
general "immediately after the function" convention?
It would have avoided at least two such bugs in this file alone since 
2.6.23...
