Subject: [PATCH] scsi: cxlflash: Refactor AFU capability checking
References: fate#322239
Patch-mainline: v4.13-rc1
Git-commit: efa1c818d3458fe97d8f83f40051518b44183234
The existing AFU capability checking infrastructure is closely tied to
the command mode capability bits. In order to support new capabilities,
refactor the existing infrastructure to be more generic.
