V4L/DVB (11074): au0828: fix i2c enumeration bug
There was a bug where enumerating the i2c for devices would result in false
positives. The root of the issue was the scanning was using SMBUS_QUICK
messages, which are zero length write requests (which our i2c adapter
implementation didn't handle). Because we never strobed any bytes onto the
bus, the status register would still contain the value from the previous
request.
Thanks to Michael Krufky <[email protected]> and Steven Toth
<[email protected]> for providing sample hardware, engineering level support,
and testing.
