Oh, you are right. Despite that the SMbus block transaction limits the maximum
number of bytes to 32, nothing prevents a user from specifying via ioctl a larger
data size than the ft260 can handle in a single transfer.

I am going to fix it in the ft260_smbus_write (with your Signed-off-by), but
perhaps we should fix it in the first place, in the i2cdev_ioctl_smbus routine?
What do you think?

Could you just give me a Reported-by tag?  Thanks!

Done, thanks!
