From: Arvind Yadav
Date: Wed May 31 2017 - 03:16:05 EST


Replace '%d' by '%zu' to fix the following compilation warning:-

drivers/i2c/busses/i2c-at91.c:277:2: warning: format â%dâ expects argument of type âintâ, but argument 5 has type âsize_tâ [-Wformat=]
dev_dbg(dev->dev, "wrote 0x%x, to go %d\n", *dev->buf, dev->buf_len);
^
