[PATCH 3/3] regulator: max8998: Remove unnecessary **rdev from struct max8998_data

From: Axel Lin
Date: Sun Mar 09 2014 - 03:32:36 EST


Now we are using devm_regulator_register(), so we don't need to allocate *rdev[]
array to store return value of devm_regulator_register. Use a *rdev variable is
enough for checking return status.
