[PATCH v2 4/9] ufs: core: Call ufshcd_add_scsi_host() later

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Call ufshcd_add_scsi_host() after host controller initialization has
completed. This is possible because no code between the old and new
ufshcd_add_scsi_host() call site depends on the scsi_add_host() call.
