When a device is not detected, the driver prints a warning message. That's ok, except for the fact that, even on newer devices that have eeprom but aren't yet supported, it prints a message saying that the device doesn't have eeprom. Fix it by having a separate message for devices with eeprom, but not yet known by the driver. Signed-off-by: -

This driver is abusing the kernel<=>userspace API, due to the lack of a proper solution for it. A discussion were done at: http://www.mail-archive.com/linux-media@vger.kernel.org/msg22196.html But there's not a solution for it yet. So, move the driver to staging, while we don't have a final solution. Signed-off-by:
