That needs some cleanups and refactoring first. To make that easier, it would be helpful if all in-kernel users would call the helper functions of the I2C core for SMBus block transfers and not open code it via the generic smbus_xfer. This series converts the three users doing that. I don't have the hardware, so these patches are only build tested. Please let me know what you think.
