Get rid of them by adding explicit forced casts.

[media] cx2341x: fix kernel oops

2014-09-21T23:56:11+00:00

The v4l2_ctrl_config struct must be zeroed before passing it to
v4l2_ctrl_new_custom(). This was always wrong, but with the recent
v4l2-ctrls.c changes this is now much more likely to lead to a
kernel bug.

This is the only place where this struct wasn't initialized properly.

[media] rc-core: remove protocol arrays

2014-07-25T22:10:43+00:00

The basic API of rc-core used to be:

	dev = rc_allocate_device();
	dev->x = a;
	dev->y = b;
	dev->z = c;
	rc_register_device();

which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:

	dev = rc_allocate_device();
	dev->x = a;
	rc_set_allowed_protocols(dev, RC_BIT_X);
	dev->z = c;
	rc_register_device();

There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).
