[SCSI] mpt2sas: Fix for issue Port Reset taking long time(around 5 mins) to complete while issued during creating a volume
This is due to the slave_configuration routine is getting called when host reset is active, and config page reads are failing, and driver attempts to added device with stale config data. To fix the issue, added error checking in slave_configure to check for configuration pages failing, and return "1" so the device is not configured. The config pages are failing if raid volume is configured while issuing a host reset, thus driver is reading stale data and proceeding to attempt to add. The fix is to return error so the volume is not configured. Signed-off-by: Nagalakshmi Nandigama <nagalakshmi.nandigama@lsi.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
