Maybe change struct dvb_device:
struct dvb_device {
struct list_head list_head;
- struct file_operations *fops;
+ struct file_operations fops;
struct dvb_adapter *adapter;
We can of course do that, but if we do that now, i will have to rework
on the changes that which i have, but considering the changes that i
have i wouldn't want to do such a change right now as marcel
explained. But we can surely go in for this, as soon as the rest of
the API changes goes in, ie, multiproto + adaptor changes
