pcc_mbox_probe(9)

💖 pcc_mbox_probe(9) — the Kernel API Manual glow-up 🎀

okay so bestie, this is a page straight out of the Kernel API Manual, and it's about pcc_mbox_probe — the lil function that gets called the moment we find a match for the PCCT platform device. and like… that's literally all it does?? it's purely there to represent the PCCT as a virtual device so it can register with the generic Mailbox framework. no cap, that's the whole vibe. it's giving "glorified registration form" energy and honestly? iconic. 💅

✨ SYNOPSIS ✨

int pcc_mbox_probe (struct platform_device *pdev );

🌸 ARGUMENTS 🌸

• pdev — pointer to the platform device that gets returned when a match is found. that's it, that's the whole argument. she's lowkey low-maintenance 🫶

⭐ RETURN ⭐

• 0 for Success
• otherwise, an errno. so like, if it's not 0, something went sideways and the errno will tell you what 😭

fr fr, check that return value. 0 = slay, anything else = go read the errno.
