Please do not use lrbp->cmd to check whether or not a command has completed.

The above looks wrong to me. How can ufshcd_mcq_nullify_cmd() identify a
command if the 'tag' argument is not passed to that function?

Please only use capitals if these are required.

Same comment here - do not use lrbp->cmd to check for completion.
Thanks,
