[PATCH v3 0/9] Use dev_err_probe in i2c probe function

[Liao Chang]

Use the dev_err_probe function instead of dev_err in the probe function
so that the printed messge includes the return value and also handles
-EPROBE_DEFER nicely.

NOTICE: dev_err_probe always print the second parameter that happens to
be the return value, hence the return errno will be removed from the
third parameter to avoid a redundant error message.

v3:
Convert all dev_err() in synquacer_i2c_probe() to dev_err_probe()
even if the return value is known to never be -EPROBE_DEFER.

v2:
1. Convert all dev_err() in lpi2c_imx_probe(), synquacer_i2c_probe(),
   mlxbf_i2c_probe() to dev_err_probe().
