Urgh. cx25840_loadfw() in cx25840_firmware.c contains this code:

        if (state->is_cx23885)
                firmware = FWFILE_CX23885;
        else if (state->is_cx231xx)
                firmware = FWFILE_CX231XX;

Unfortunately firmware is a global string module option, initially setup to
contain the 'normal' cx25840 firmware name.

So loading a cx23885 or a cx231xx will overwrite that string and if ivtv is
loaded afterwards it tries to load the wrong firmware.

Sigh...

I'll see if I have time to fix this today or tomorrow.

Regards,

	Hans
