Hi

Thanks for processing this.

The 5.10/scsi-queue branch seems to be missing the following fix.  If you cherry
pick that, then it applies.


commit 8da76f71fef7d8a1a72af09d48899573feb60065

    Intel EHL UFS host controller advertises auto-hibernate capability but it
    does not work correctly. Add a quirk for that.
