status of the USB w9968cf.c driver in kernel 2.6?

status of the USB w9968cf.c driver in kernel 2.6?

[Adrian Bunk]

I noticed the following regarding the drivers/usb/media/ov511.c driver:
- it's not updated compared to upstream:
- there's no w9968cf-vpp module in the kernel sources

Are there any reasons why the upstream driver can't be resynced with the
kernel?

w9968cf-vpp is an optional, gpl'ed module, which can not be included in the 
mainline kernel, as I explained in the documentation of the driver.

Sorry, my fault.
I confused this with a different driver.

  Please keep in mind that official kernels do not include the second 
  module for performance purposes.

What exactly does this mean?

Is it useful or not?

Frame decoding/decompression should be done in userspace, although you can 
still download and use a separate kernel module.

Yes

If it's deprecated to do this in a kernel module, shouldn't at some time 
the EXPORT_SYMBOL's for the decoding/decompression module be removed 
from the kernel?
