Bug Description

I hope this is the right team!

In https://github.com/torvalds/linux/blob/master/drivers/i2c/busses/i2c-omap.c, in the function omap_i2c_xfer_msg - there's an initial test to return EINVAL if msg->len == 0

This seems reasonable but breaks communications with unreasonable devices like the HIH6130 (http://www.mouser.com/pdfdocs/I2CCommunications.pdf) which expects what is effectively a zero length write: just the address then a stop bit.

Is it possible to remove this test?
