From 9023ed8d91eb1fcc93e64dc4962f7412b1c4cbec Mon Sep 17 00:00:00 2001 From: Daniel Palmer Date: Thu, 3 Oct 2024 13:29:47 +1000 Subject: scsi: wd33c93: Don't use stale scsi_pointer value A regression was introduced with commit dbb2da557a6a ("scsi: wd33c93: Move the SCSI pointer to private command data") which results in an oops in wd33c93_intr(). That commit added the scsi_pointer variable and initialized it from hostdata->connected. However, during selection, hostdata->connected is not yet valid. Fix this by getting the current scsi_pointer from hostdata->selecting.
