Subject: [PATCH] obsolete config in kernel source (DVB_DIBCOM_DEBUG)

Hi all!

	As part of the VAMOS[0] research project at the University of
Erlangen we're checking referential integrity between kernel KConfig
options and in-code Conditional blocks.

	By this we discovered the config Option DVB_DIBCOM_DEBUG,
which was dropped while removing the dibusb driver in favor of dvb-usb
in 2005. However it remaind existant at some places of the kernel
config.

	Probably one should be a bit more agressive here as the dprintk
macro now expands to a do{}while(0) unconditionally so all blocks
using them can also be dropped to remove in-tree cruft but the patch
does a first cleanup.

	Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

Regards

	Christoph Egger
