Hi Martin,

This patch series introduces enums for the SAM, message, host and driver
status codes and hence improves static type checking by the compiler.
Please consider this patch series for kernel v5.14.

Thanks,

Bart.

Changes compared to v1:
- Modified the comment block at the start of the enum exec_status definition
  in libsas.h.
- Changed the __SAM_STAT_ prefix into SAS_STAT_ for the SAM status codes that
  are also used in the SAS code.
- Restored the reverse-Christmas tree style in two functions.
- Renamed enum host_status and driver_status into enum scsi_host_status and
  scsi_driver_status respectively.
