Currently the I2C core reports only a negative number on errors.
However some of the users in case of errors want to re-transfer only
the remaining bytes.

The patch series tries to add a actual field to the msg which
can be checked by the user.

Also a patch to implement the actual bytes transferred in case of
i2c-omap.


Felipe Balbi (1):
  i2c: omap: implement handling for 'actual' bytes transferred

Shubhrajyoti D (2):
  i2c: add 'actual' field to struct i2c_msg
  i2c: inititalise the actual transferred to zero
