This is a duplicate of bug #131703 for RHEL 2.1:
-const char *aac_driverinfo(struct Scsi_Host *host_ptr)
+const char *aac_info(struct Scsi_Host *shost)
- struct aac_dev *dev = (struct aac_dev *)host_ptr->hostdata;
+ struct aac_dev *dev = (struct aac_dev *)shost->hostdata;
Which is the same code that was in RHEL3, pre-fix of that particular bug.
Patch seems to be included in:
