V4L/DVB: pvrusb2: New feature to mark specific hardware support as experimental
This adds a flag in the device attribute structure which can be used to mark support for a particular device as experimental. Any devices flagged in this way, when encountered at run-time, will generate a warning message to the kernel log.
