This looks like it is related to this patch:

commit d66b94b4aa2f40e134f8c07c58ae74ef3d523ee0
Author: Patrick Boettcher <pb@linuxtv.org>

    V4L/DVB (11829): Rewrote frontend-attach mechanism to gain noise-less 
deactivation of submodules

    This patch is reorganizing the frontend-attach mechanism in order to
    gain noise-less (superflous prints) deactivation of submodules.

    Credits go to Uwe Bugla for helping to clean and test the code.

    Signed-off-by: Patrick Boettcher <pb@linuxtv.org>
    Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>



All frontend-attach related code is wrapped by ifdefs like this:
#if defined(CONFIG_DVB_MT312_MODULE) || defined(CONFIG_DVB_STV0299_MODULE)
<CODE>
#endif

So this code will only be compiled if one of the two drivers is compiled as a 
module, having them compiled in will omit this code.

Trent Piepho seems to already have a patch for this, but it is not yet merged 
into the kernel.

Matthias
