Hi,
nice to see someone else interested in the I2C & DMA topic.
Please check this series which I sent out recently:
"[RFC PATCH v4 0/6] i2c: document DMA handling and add helpers for it"
In that series, I proposed...
> 3. kmalloc data buffer instead of local variables buf in function
> i2c_smbus_xfer_emulated(...)
... this solution. Although I have to check Mauro's general response to
the series first. I'd be interested in what you think of the series,
too.
Kind regards,
Wolfram
