The ipr driver has a sysfs attribute which can be used to
adjust the logging level of the driver for error events.
The error response data for commands can be dumped by
increasing the logging level of the ipr driver. This
currently only works for JBOD passthrough devices.
This patch enables this function for all devices, including
RAID devices, to aid in debugging problems.
