Just repeating this again due to updated recipients list:

This new approach now means that Scsi_host cleanup (scsi_host_put)
happens after ufshcd's hba->dev cleanup and I am not sure if this
approach has wider implications (in particular if there is any
underlying assumption or requirement for the Scsi_host device to
clean up before the ufshcd device).

Simple testing using a few iteration of manual module bind/unbind
worked, as did the error handling / cleanup during init. But I'm
not sure if that is sufficient testing for the changed release
ordering.

Cheers,
