msgdma_probe(9)

🎀 NAME 🎀

okay so bestie, this is msgdma_probe(9) from the Kernel API Manual, and we’re gonna read it together like it’s the group chat’s pinned message. It’s the driver probe function, and the whole vibe is: one argument, one int return type in the synopsis, and a SEE ALSO list that ate. 💅

✨ SYNOPSIS ✨

int msgdma_probe (struct platform_device *pdev );

yes, that’s the exact signature, spaces and all—don’t @ me.

🦋 ARGUMENTS 🦋

• pdev — Pointer to the platform_device structure.

💜 RETURN 💜

Literally nothing is listed here, bestie. The RETURN section is empty in the original, so I’m not inventing return values or pretending there’s more. The synopsis says int, and that’s the only return-ish detail on the page. 😭
