This patch was authored by Nick,
but I assume it is trying to address issue due to I2C adapter limitation
which following patch in this series is already doing
"Input: atmel_mxt_ts: Limit the max bytes transferred in an i2c transaction"

I will extend patch "Input: atmel_mxt_ts: Limit the max bytes
transferred in an i2c transaction"
to also cover this case.

Thanks,
Jiada
