incomplete type?!?

incomplete type?!?

[Giuliano Pochini]

I can't compile spin_lockxxxx(lock):

echoaudio.c:237: dereferencing pointer to incomplete type

I try to compile my module with the same args, defines and includes of
azt3328.c. Spinlock operations expands to exactly the same stuff
according cpp, but azt3328 compiles fine. What am I missing ?

Bye.

did you include the correct kernel header files?
i guess spinlock_t is not defined properly.

Yes... I believe. I also copied the #include's from azt3328.c and
I added <spinlock.h>. I hate problems with header files #:(


Bye.

you mean <linux/spinlock.h>, right?

anyway, it's better to show the code and the exact error messages for
debugging if you have nothing against...  it might be a simple typo,
such as the forgotten '&' etc.
