| Subject: fsi: occ: Don't accept response from un-initialized OCC |
| |
| From: Eddie James <eajames@linux.ibm.com> |
| |
| [ Upstream commit 8a4659be08576141f47d47d94130eb148cb5f0df ] |
| |
| If the OCC is not initialized and responds as such, the driver |
| should continue waiting for a valid response until the timeout |
| expires. |
