Since installing kernel 3.17.0-1.gc467423-desktop (on openSuSE 13.1) my
xc4000/zl10353/cx88 based DTV card has failed to initialise on boot.

The following messages are from dmesg;

[ 78.468221] xc4000: I2C read failed
[ 80.074604] xc4000: I2C read failed
[ 80.074605] Unable to read tuner registers.

[ 151.305370] cx88[0]/2: cx8802 probe failed, err = -22

It worked with 3.16.3-1.gd2bbe7f-desktop on the same machine.

Regards,
Rodney.
