cx23885: DVBSky S952 dvb_register failed err = -22

Hi,

using linux-3.19.1-1 (Archlinux) I get the following output while
booting without the media-build-tree provided by DVBSky:

Obviously there are no device in /dev/dvb. Using the media-build-tree
works just fine though. The following firmware files are installed in
/usr/lib/firmware:
dvb-demod-m88ds3103.fw
dvb-demod-m88rs6000.fw
dvb-demod-si2168-a20-01.fw
dvb-demod-si2168-a30-01.fw
dvb-demod-si2168-b40-01.fw
dvb-fe-ds300x.fw
dvb-fe-ds3103.fw
dvb-fe-rs6000.fw
dvb-tuner-si2158-a20-01.fw

Output of lspci -vvvnn:

I also set the module parameters debug, i2c_debug, irq_debug and
irq_debug in cx23885.
The output is pretty verbose and can be found here:

Thanks,
