[I2C] About warning 'DMA-API: device driver maps memory from stack'

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
