V4L/DVB (5428): M920x: Detect zero-length I2C messages and fix a typo
Change a 00 to just 0
Detect zero-length I2C messages and return not supported. I think I know
how to send one, but the problem is getting the slave's ack. The only
point of a zero-length message is for probing; too see if the slave will
ack its address. Since we don't know how to get the ack, we can't
support zero-length messages in a useful way, so it's probably best to
just return not supported for them.
