Minwoo,

> This patchset introduces add support for MCQ introduced in UFSHCI 4.0.
> The first patch adds a simple helper to get the address of MCQ queue

> mandatory vops callback functions required at MCQ initialization
> phase. The last one is to prevent a case where number of MCQ is given
> 1 since driver allocates poll_queues first rather than I/O queues to

Applied to 6.11/scsi-staging, thanks!
