i2c & kernel 4.4.9-1 : possible bug ?
Hi,
In my system with kernel 4.4.9, i can see this message in log :
i2c i2c-0: sendbytes: NAK bailout.I see this also :
cx22702_writereg: error (reg == 0x0d, val == 0x00, ret == -5)It corresponds to my Hauppauge HVR3000 TV card.

Re: i2c & kernel 4.4.9-1 : possible bug ?
I do not know about that card, but a NAK means negative acknowledge. The i2c bus is a two wire bus with a clock line and a data line. When the bus controller addresses a chip on the bus, the controller sends that chip an address, a register number, and an indication whether it is going to be reading or writing that register; then it performs an acknowledge. During the acknowledge, the controller lets go of the data line (stops driving it) and 'listens' to the bus. If there is a chip on the bus at the address that was sent, and if that chip is capable of performing the specified read or write operation on the specified register, the chip will take control of the data line and will hold it low. If it does not (negative acknowledge) the data line "floats" high. If the controller sees the line go high during the ack cycle, it knows either there is no chip at that address, or the chip is refusing the command. Once the controller determines the ACK/NAK, it ends the acknowledge cycle by pulling the clock low at which point the target chip will release the data bus.
So, either the driver seems to be trying to write a 0x00 to register 0x0d of a chip called cx22702. Any chance that Hauppauge changes chips from version to version?

That, or not all Hauppauge HVR3000 demodulators are the same. Both are a distinct possibility.
It probably should be brought to the attention of the upstream developers in either event.
