Can,

You seem to be sending duplicates of almost every mail which makes it
hard for me (and patchwork) to track your series. The mails are
identical except for Message-Id:.

Also, don't resubmit patches just to add Reviewed-by: tags. Patchwork
will pick up the tags. Only resubmit if you are making changes. And if
you do, use -vN to bump the version.

[PATCH] scsi: ufs: Give an unique ID to each ufs-bsg

[Can Guo]

Considering there can be multiple UFS hosts in SoC, give each ufs-bsg an
unique ID by appending the scsi host number to its device name.

Looks good,

This should also get a Fixes: tag so that it gets backported.

Consider a platform which has an embedded UFS device and supports a UFS 
card meanwhile.
This conbination is very popular nowadays. BTW, 845 started supporting 
two UFS hosts 3 years ago.

Thanks,
