During run-time the driver can be very chatty and spam the system
kernel log. Various print statements can be limited and/or moved
to development-only mode. Additionally, numerous prints can be
converted to trace the corresponding device.
The following changes were made:
- pr_debug to pr_devel
- pr_debug to pr_debug_ratelimited
- pr_err to dev_err
- pr_debug to dev_dbg

Changes mostly look fine, further comments below.

Minor nitpicking: mention that you fix these in the commit message.

Why has the message changed from scsi_set_resid to scsi_done, and should
the message be moved to immediately before the scsi_done call?
