KWorld DVB-T 305U now working

[Dean]

My dmesg gave the following (excerpt) when I connected my KWorld 305U.

em28xx #0: Identified as KWorld DVB-T 305U (card=47)
em28xx #0: 

em28xx #0: The support for this board weren't valid yet.
em28xx #0: Please send a report of having this working
em28xx #0: not to V4L mailing list (and/or to other addresses)

So here I am, making this announcement.  Do I even have the correct mailing list?  What is the next step towards re-classifying the KWorld 305U as a supported device?

Regards.

Hello.

I have been writing this FM radio driver and I'm now trying to implement
it as a platform driver that passes IOCTL calls to a subdevice driver
that handles the communication with the hardware etc. 

For IOCTLs there's a macro v4l2_device_call_until_err in v4l2-device.h
that makes the calls pretty convenient to write. But for file operations
there's not such define.

This leads me to the question: should there be such a define for fops or
should they be treated in a different way? To me the IOCTL callbacks and
the file operation callbacks look pretty similar...

Cheers,
Matti
