[linux-dvb] Re: Problem using the tuner on my Nebula card

[Mikael Rosbacke <rosbacke@nada.kth.se>]

Tried it and it works to go back version 1.12. Thanks for the advice.
I had had another look at the code and it turns out the is a difference in 
some of the new code. After some analysis, I changed line 750 in version 1.13 
of nxt6000.c:
dvb_register_frontend(nxt6000_ioctl, i2c, (void *)nxt, &nxt6000_info);

into:
dvb_register_frontend(nxt6000_ioctl, i2c, (void *) (*(u32*)nxt), 
&nxt6000_info);

and it works. I'm not sure why they pass a u32 value as a void pointer but 
thats the way it is done in version 1.12 and if the code in 
dvb_register_frontend hasn't changed, this should be right.

fine .DS

Done.


Sorry, I gave the wrong info in the last message - it is
nxt6000.c that is broken, you need v1.12 of it.
