	The find_next_zero_bit() is called with the from and to arguments in the wrong order. This results in the function always returning 0, and all media devices being registered with minor 0. Furthermore, mdev->minor is then used before being assigned with the find_next_zero_bit() return value. This really makes sure we'll always use minor 0. Fix this and let the system support more than one media device.

2011-03-22	[media] media: Media device node support	Laurent Pinchart
	The media_devnode structure provides support for registering and unregistering character devices using a dynamic major number. Reference counting is handled internally, making device drivers easier to write without having to solve the open/disconnect race condition issue over and over again. The code is based on video/v4l2-dev.c.
