Subject[PATCH 1/5] ARM: imx: gpc: Do not print error message for EPROBE_DEFER
Date
The pu regulator request will return -EPROBE_DEFER if it has a supply
from PMIC and this supply is not yet registered. This does not represent
an error since the driver will call probe again later, so only print a
warning message in this case.
