Subject: [PATCH] scsi: cxlflash: Setup OCXL transaction layer
References: FATE#325192
Patch-mainline: v4.18-rc1
Git-commit: c52bf5b384532ebc49deea16daf65c5cd1afbab2
The first function of the link needs to configure the transaction layer
between the host and device. This is accomplished by a call to the OCXL
provider services.
