I'm sorry. There was a misunderstanding in my previous comment.

The UFS_CMD_ERR stands for "command completion error."
I wanted to make it consistent with the other enums.
For example, query errors are defined as UFS_QUERY_ERR,
and Task Management errors are defined as UFS_TM_ERR.

I hope to use UFS_CMD_ERR for the same classification purposes
as UFS_CMD_SEND or UFS_CMD_COMP.
Therefore, UFS_CMD_ERR can be used for logging SCSI or UIC commands.

Thank you.
DooHyun Hwang.
