Subject: SCSI: ipr: Need to reset adapter after the 6th EEH error
From: "wenxiong@xxxxxxxxxxxxxxxxxx" <wenxiong@xxxxxxxxxxxxxxxxxx>
commit 96b04db9f2c16e77c31ef0e17e143da1e0cbfd78 upstream.
Add reset adapter after the 6th EEH errors in ipr driver. This triggers
the adapter reset via the PCI config space even when the slot is frozen.
