🌸 SYNOPSIS 🌸

void scsi_msg_to_host_byte (struct scsi_cmnd *cmd , u8 msg );

🧚 DESCRIPTION 🧚

okay so here's the tea: this function translates the SCSI parallel message byte into a matching host byte setting ✨ Literally its whole job, and it ate.

A message of COMMAND_COMPLETE indicates a successful command execution 💚 — slay, we love a happy ending. Any other message indicates an error 😭 so like, if it's not COMMAND_COMPLETE, it's giving struggle.

And here's the part where you have to pay attention bestie 🙈 — the messages themselves only have a meaning for the SCSI parallel protocol. Periodt. That's why this function exists at all: it translates them into a matching host byte value for SCSI EH 💅 iykyk.
