💖 pm8001_prep_sas_ha_init(9) 💖

okay so bestie, we're in the Kernel API Manual today and this page is literally all about one little function that does the glow-up prep for your SAS host adapter. no cap, it's the "get your room ready before the party" step.

---

✨ NAME ✨

pm8001_prep_sas_ha_init — it allocates memory in the general hba struct && inits them. like, both things. the allocating AND the initialising. she's doing the most, honestly. 💅

---

🌸 SYNOPSIS 🌸

int pm8001_prep_sas_ha_init (struct Scsi_Host *shost , const struct
pm8001_chip_info *chip_info );

returns an int, takes two args, very demure, very mindful. 🎀

---

🦋 ARGUMENTS 🦋

• shost — the scsi host 🫶 and just so you know, it's been allocated outside already, so don't come for her, she's not the one doing that allocation.
• chip_info — our ha struct ✨ that's it, that's the whole vibe. it's ours.
