[PATCH 0/2] don't check number of I2C messages in drivers

The core does it now, we can simplify drivers.

Wolfram Sang (2):
  i2c: ibm_iic: don't check number of messages in the driver
  i2c: opal: don't check number of messages in the driver

Since commit 1eace8344c02 ("i2c: add param sanity check to
i2c_transfer()") and b7f625840267 ("i2c: add quirk checks to core"), the
I2C core does this check now. We can remove it here.

Only build tested.

It will get boot tested by me once it's in linux-next, which hopefully
is sufficient for a patch like this.
