This is a card with RDS capabilities. RDS specifications didn't change from V4L1 to V4L2, so that part should be OK. This patch changed the following stuff: * The device can be opened multiple times. That's necessary because there are at least a radio application and an RDS application (rdsd) that want to open() the device. * Added a poll() function. Every character device should have that, and rdsd expects it as it uses select() on that file descriptor. * Converted the ioctls to V4L2. MUTE is not implemented correctly as the card doesn't seem to have a special bit for that. Probably there are a few more ioctls that should at least return 0 or an error. As I do not own such a card, I couldn't test anything. If there is anybody out there who owns such an ancient card, please test and report. I just checked that the code compiles.
