[pvrusb2] no audio with PAL and tda9887

[Michael Roitzsch]

Hi Mike,

I have my weird no audio problem isolated: It turns out to be a  
collision of your driver and the em8300 driver for my DXR3 (aka  
Hollywood+) MPEG decoder card. When I remove this driver from the  
kernel tree, power cycle the pvrusb2 (just a reboot is not enough!)  
and reboot, everything works fine (except for my DXR3, of course). If  
I put the em8300 module back, the pvrusb2 is silent again (picture  
still works) at the next reboot.

This is good news so far, however, I would like to get this secondary  
issue fixed to run both devices at once. A possible starting point is  
that both have an internal I2C bus. Is it possible that the em8300  
driver does some wrong I2C things that somehow move the pvrusb2 in a  
broken state?

I also have two notes on the latest driver snapshot, which I will  
post in the appropriate thread.

Michael
