The supplied buffer might be on the stack and we get the following error

[ 3.312058] at91_i2c e0070600.i2c: rejecting DMA map of vmalloc memory

Use i2c_{get,put}_dma_safe_msg_buf() to get a DMA-able memory region if

I'm not sure if or which Fixes: tag I should add to this patch. The issue seems to be since a very long time, but nobody seem to have triggered it.
FWIW, I'm using the sff,sfp driver, which triggers this.
