[PATCH] i2c: i2c-mv64xxx fix transaction abortion
When the i2c-mv64xxx i2c driver is signalled to abort a transaction,
it aborts it immediately by issuing a stop condition on the bus.
This violates the i2c protocol and can cause what appears to be an i2c
bus hang. This patch delays issuing the stop condition until the i2c
device can reasonably expect a stop condition.
Also includes a minor fixup.
