Subject[PATCH] i2c: mxs: change error printing to debug for mxs_i2c_pio_wait_xfer_end
Message-ID<tN8ql-31c-5@gated-at.bofh.it>
Instead of printing errors after mxs_i2c_pio_wait_xfer_end returns with
an error code just print a debug message.

NAKs and timeouts can occur in this situation normally, so do not treat
them as errors.
