Thanks Cosmo for the catch.

And, IMHO, the root cause is the memset() on part buffer called in
complete_response() is not quite correct. In the current implementation, the
complete_response() should only be called when the READ is completed, ie:
only on I2C_SLAVE_STOP of READ transaction, otherwise all the info of
current on-going request will be mistakenly cleared as in this case.

This patch is good and I wonder if we can make this a bit further as below?

Yes, this is probably more future proof.

Can you send me a formal patch, with a "Found-by:" for Cosmo? I'll
replace Cosmo's patch.


Thanks Corey,

Will send the formal patch later.

Thanks,
