Kumar" Currently, scsi_host_put() is being called prematurely in the remove path and is missing entirely in an error cleanup path. Move the usage on remove to be the last cleanup action taken and introduce a call to scsi_host_put() in the one initialization error path that does not use remove to cleanup.
