[PATCH] i2c: mxs: change error printing to debug for mxs_i2c_pio_wait_xfer_end

From: Michael Thalmeier
Date: Wed May 31 2017 - 05:41:33 EST


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.
