💅 scsi_add_host_with_dma(9)

okay bestie, so this one lives in the Kernel API Manual — yes, we're in kernel-land now, grab your iced coffee 🧊☕ because we're registering a SCSI host, but like… with a DMA device attached. main character energy fr fr.

✨ NAME ✨

scsi_add_host_with_dma — add a scsi host with dma device 🦋

---

🎀 SYNOPSIS 🎀

int scsi_add_host_with_dma (struct Scsi_Host *shost , struct device *dev
, struct device *dma_dev );

---

🌸 ARGUMENTS 🌸

• shost — the scsi host pointer you're adding, like the whole point of the function 💖
• dev — a struct device of type scsi class, iykyk
• dma_dev — the dma device for the host, slay 🔥

---

💀 NOTE 💀

ngl, you rarely need to worry about this one unless you're in virtualised host environments — so bestie, just use the simpler scsi_add_host function instead. it's giving "why are you doing the hard version" 🙈

Return value: 0 on success / != 0 for error ⭐ (so if it's not zero, something went wrong, no cap)
