Zero-length offsets are not properly handled by the driver. When a read operation with a zero-length offset is started, a START condition is asserted, and since no offset bytes are transferred, a repeated START is issued immediately after, which confuses the controller. To fix this, we send the first START only if any address bytes need to be sent, and keep track of the expected start status accordingly.
