[PATCH] dvb: TTUSB-Budget DVB driver update

From: Michael Hunold <hunold@linuxtv.org>

- dvb-ttusb-budget: Fixed i2c code to detect nearly all errors

- dvb-ttusb-budget: Added "V 2.1" to prevent warning message on driver load

- dvb-ttusb-budget: Some printks turned into dprintks

- dvb-ttusb-budget: Removed __initdata.  It is now possible in kernel 2.6
  to compile the DVB drivers into a monolithic kernel.

- dvb-ttusb-budget: Fix for failing urb submission under 2.6 kernels
