[Accel-config] [PATCH v1] accel-config: Skip printing error if cmd status register is not set

From: Ramesh Thomas <ramesh.thomas(a)intel.com>

Library functions do their own checking and return errors without
issuing commands to the hardware. Command status register retrieved
from "cmd_status" sysfs attribute may not be set in such cases. Return
NULL from function that retrieves the error status to indicate this.
