tuner-types.h symlink

tuner-types.h symlink

[Ben Caldwell]

This is my first post on the v4l list, so hi everyone!

I just got a warning compiling the latest v4l source from mercurial, there
was a missing symbol "tuner_count" in "tuner-simple.ko"

I fixed the problem by adding a symlink in v4l-dvb/v4l:

*$ ln -s ../linux/include/media/tuner-types.h  tuner-types.h*
**
I'm hoping that someone here can check that this is indeed the right thing
to do and commit a change to the repository for me if it is.

Thanks,

Ben Caldwell

Which module's build produced this warning?  Can you show us the warning?

Here is the output from make with the symlink removed again:

I found the definition for tuner_count in tuner-types.h, and saw that
tuner-simple.c had an #include "tuner-types.h" so I added the symlink to see
if that helped.
Neither of the two warnings above came up the next time so I assume it did
help.

I've been having troubles with this card only showing one tuner in mythtv
lately, and came across this in my search for a fix.
